Reading Your Daily Radiation Treatment Record Sheet — What Every Line Actually Means
Medically reviewed by Dr. Kirti Ranjan Mohanty, Radiation Oncologist, MBBS · MD (Radiation Oncology), Senior Consultant · Last reviewed August 2026
Your daily radiation treatment record sheet is the working log of your course. Each row is one session: the date, the fraction number, the dose delivered, the machine used and the initials of the therapists who treated you. Read together, the rows show exactly how much of the planned course is done.
- One row is one session — date, fraction number, treatment site, the dose given that day, the machine and two sets of staff initials — nothing on the row is a test result.
- Cumulative dose is the number to watch — the running total tells you how far through the planned course you actually are, whatever the calendar says.
- Asking for a copy is routine — in general practice at Indian centres you or an authorised relative can request your record, and many teams simply let you photograph it weekly.
- Where your treatment actually happens — your radiotherapy is delivered at an NABH-accredited partner centre; CION Cancer Clinics coordinates your treatment plan, your oncology team and your care throughout.

What is the daily radiation treatment record sheet?
It is the delivery log for your radiotherapy course. One row is one session. Each row records the date, the session number, the treatment site, the dose given that day, the running total, the machine used and the initials of the therapists who treated you. It is a record of what happened, not a result.
Most people are handed this card, or shown it on a screen, without anyone reading it aloud. It gets initialled twice a day by staff who already know what every column means, and it goes back in the file. That is where the feeling of being processed rather than informed comes from — not from anyone withholding anything, but from a document nobody was asked to explain.
Read properly, the same card becomes something you can follow week by week: a progress bar with a start, an end and a visible middle. That is all this page is for. Once you know which column is the fraction count and which one is the running dose, you can answer your own question about how far along you are, on any day, without waiting for a review appointment.
Your radiotherapy is delivered at an NABH-accredited partner centre, and the record sheet is that centre’s clinical document, kept and signed by its treating team. CION Cancer Clinics coordinates your treatment plan, your oncology team and your care throughout — we do not own or operate radiotherapy equipment ourselves.
This page describes general record-keeping practice at radiotherapy centres in India so you can read your own sheet with more confidence. Layouts differ from centre to centre. It is patient information, not legal advice, and it does not replace what your own treating team tells you about your plan.
Did you know?
Your record sheet is not just paperwork for the file. Radiotherapy quality-assurance practice described by ASTRO and the American Association of Physicists in Medicine includes an independent review of the treatment chart by a medical physicist during the course, usually weekly, comparing what was actually delivered against what was prescribed. The sheet you are being handed is the document that check is run against.
What do the daily entries on my radiation record sheet mean?
Nine things you are likely to find on the row for today. Layouts vary; the vocabulary does not.
Each row is one session, read left to right. Date, fraction number, treatment site, dose given that day, cumulative dose, machine, monitor units, imaging done, and two sets of staff initials. A notes column carries anything unusual — a missed day, a gap, a change in setup.
The day the session was actually delivered
Not the day it was scheduled. If the two differ, the gap should show up in the notes column with a reason beside it.
Which session this is, out of the planned total
Often written as a fraction, such as 12/25. A fraction is simply one day’s share of the total dose your prescription divides up.
The part of the body being treated today
Sometimes a body-part name, sometimes a plan or field label the physicist assigned. If two sites are being treated, expect two entries.
The dose delivered in this single session
Written in gray (Gy) or centigray (cGy). One gray equals one hundred centigray, which explains most numbers that look surprising.
The running total delivered so far
The most useful figure on the page. It tells you how much of the planned total has actually been given, whatever the calendar says.
Which treatment unit you were on that day
Centres with more than one machine record it, so your course can be reconstructed exactly. A change of unit is normally planned, not an error.
A machine-side number, written MU
Monitor units are how the machine measures its own beam output. They are for the physicist and the therapists, not a number you need to interpret.
Verification pictures taken before treatment
A portal image or a cone beam scan checks your position against the plan. These are setup checks, not scans reporting on your cancer.
Usually two sets, and that is deliberate
Two radiation therapists commonly sign each session, because setup and delivery are independently confirmed rather than left to one person.
What is cumulative dose, and how do I read it?
Cumulative dose is the running total of radiation delivered so far. Your prescription sets a total and divides it into daily fractions. The cumulative column adds up what has actually been given. It shows how far through the planned course you really are, independent of how many days have passed.
Here is the same idea as a week-by-week walk-through. The numbers below are an illustrative example only — a common way of writing a course out, not a prescription and not a recommendation. Your own total, your own dose per session and your own number of sessions are set by your radiation oncologist for your situation, and the figures on your sheet are the only ones that describe your treatment.
| Point in the course | Sessions done | Dose that week | Cumulative dose | What the sheet is telling you |
|---|---|---|---|---|
| End of week 1 | 5 of 25 | 10 Gy | 10 Gy | One fifth delivered. Skin and energy usually still unchanged at this point. |
| End of week 2 | 10 of 25 | 10 Gy | 20 Gy | Two fifths delivered. The weekly review column should now have entries in it. |
| End of week 3 | 15 of 25 | 10 Gy | 30 Gy | Past halfway. This is where most people start asking how much is left. |
| End of week 4 | 20 of 25 | 10 Gy | 40 Gy | Four fifths delivered. Side-effect notes in the margin usually increase here. |
| End of week 5 | 25 of 25 | 10 Gy | 50 Gy | The planned course is complete. The sheet closes; follow-up is a separate record. |
Two things people get wrong when they first read this column. First, the units: if a figure looks a hundred times too big or too small, check whether the column is written in gray or centigray before you worry. Second, missed days: a gap does not add dose to another day and does not change the planned total. It moves your finishing date. If a session is missed, ask the team the same day what that does to your schedule, and write the answer on your own copy.

Bring your record sheet to a free second opinion
A specialist can read the delivery log and the plan together, and tell you plainly what has been given so far — free, confidential, no obligation.
What should I track on my own copy, week by week?
Six steps, about ten minutes once a week, usually on the day of your weekly review.
Keep your own copy and record five things: the fraction count, the cumulative dose, every gap and its reason, the dates of your weekly checks, and one line a day on how you feel. That is enough to walk into any review, or any second opinion, able to answer questions from your own notes.
Ask for your own copy, or photograph the sheet each week
At the end of each week ask the radiation therapist whether you may photograph the record sheet, or request a copy through the medical records desk. Centres handle this request routinely. A dated photo gallery on your phone is a perfectly usable record.
Write the session count as a fraction, not a number
Twelve of twenty five tells you something. Twelve on its own does not. Writing it as a fraction turns the sheet into a progress bar you can actually read, which is the whole point of keeping your own copy.
Copy the cumulative dose against the planned total
Note the running total from the cumulative column and the total dose your prescription is aiming for. Check the unit written at the top of the column, because gray and centigray are both used and they differ by a factor of one hundred.
Log every gap, with the date and the reason
Public holidays, machine servicing, a low blood count, a fever, transport from a district town. Write down what happened and what the team said about making the day up. Gaps are the detail most often forgotten by the time anyone asks.
Note the dates of your weekly review, weight check and blood tests
A weekly on-treatment review by the radiation oncologist is standard practice in external beam radiotherapy. Recording those dates lets you see at a glance whether the routine checks are happening on schedule.
Add one line a day on skin, energy and anything new
A single sentence is enough. Anything sudden or severe is not a diary entry, it is a phone call: ring your treating team or the helpline on 1800 202 8726 the same day rather than waiting for your next session.
Not comfortable asking in English? Ask your care coordinator to come to the console with you — Telugu-speaking coordinators do this with district families every week, and they know which staff member on the floor can answer a records question fastest.
Record sheet, treatment summary or completion letter — which document says what?
A general comparison of the three radiotherapy documents families most often confuse. Names differ between centres.
| Question | Daily treatment record sheet | Radiotherapy treatment summary | Completion or discharge letter |
|---|---|---|---|
| What it is | A live delivery log, one row per session, signed as you go | A one-page technical summary of the whole course | A clinical letter describing what was done and what happens next |
| When you see it | Every single treatment day, at the console | At or shortly after the last session | At the end of the course, or at your first follow-up |
| What it shows | Date, fraction number, site, daily dose, cumulative dose, machine, imaging, staff initials | Total dose, number of fractions, technique, treatment site, start and end dates | The clinical picture: what was treated, how you tolerated it, follow-up plan |
| What it does not show | Any interpretation — it is a log, not an opinion | Day-by-day detail, gaps or who treated you | The technical dose detail another oncologist would want |
| Why you need it later | To reconstruct exactly what was delivered and when | The single most important document to carry to any future oncologist | To explain your course to a doctor who was not involved |
If you keep only one thing, keep the treatment summary — any radiation given in the past changes what can safely be given to the same area in the future, so a future team will ask for it. Keeping the record sheet as well simply means you can answer the follow-up questions too.
What if something on the record sheet looks wrong?
Ask the same day, at the console, pointing at the line. Most apparent errors are a unit difference, an abbreviation or a correction already made further down the page. Ask the radiation therapist or the medical physicist what that specific entry means rather than describing it later from memory.
Two habits make this easy. Point at the row instead of paraphrasing it, and ask what the entry means rather than announcing that it is wrong. Radiotherapy teams field records questions constantly, from insurers, from auditors and from patients, and a factual question gets a factual answer. Raising a query about your own record is routine and it will not change how you are cared for.
If you want a copy, ask the front desk or the medical records department how their centre prefers to handle it. In general practice at Indian hospitals your treatment record forms part of your medical record and can be requested by you or an authorised relative, sometimes on a written application and sometimes for a small administrative charge. Many teams will simply let you photograph the sheet at the end of each week, which is quicker for everyone. This is a description of general practice, not legal advice; if you need a formal position on records access or on a consent form you have signed, ask the hospital’s records department or take independent advice.
One thing worth separating out: the record sheet records delivery, and it aims to document what was given, not to judge whether the plan itself was the right one. If your real question is about the plan rather than the paperwork, that is a clinical second opinion — a different request, and one you can make without leaving your current centre. Bringing your record sheet and your treatment summary to that conversation is what makes it useful, because the reviewing oncologist can see exactly what has already been delivered.
Anything sudden or severe is not a note for your diary. Heavy bleeding, breathlessness, a high fever, a sudden severe pain or a sharp drop in how much you can drink or swallow needs a call to your treating team or to 1800 202 8726 the same day, not an entry on a sheet.

What do the daily entries on a radiation treatment record sheet mean?
Each row on the sheet is one treatment session. Read left to right you will usually find the date, the session or fraction number, the treatment site, the dose delivered that day, the running cumulative dose, the machine or unit used, and the initials of the two radiation therapists who set you up and treated you. Many sheets also carry a column for imaging done that day, such as a portal image or a cone beam scan, and a notes column where a missed day or a change is recorded. Nothing on the sheet is a diagnosis or a result. It is a delivery log: a record of what was given, when, and by whom.
What is cumulative dose on my radiation record sheet?
Cumulative dose is the running total of radiation delivered so far, added up across every session you have completed. Your prescription sets a total dose and divides it into a fixed number of daily fractions. The cumulative column tells you how much of that total has actually been given. It is the most useful number on the page, because it shows how far through the planned course you really are, independent of how many days have passed on the calendar. If you miss a day, the cumulative figure does not move that day. The planned total does not change either. What changes is the date you finish.
What is the difference between Gy and cGy on my record sheet?
They are the same unit written at different scales. Gray, written Gy, is the standard unit of absorbed radiation dose. Centigray, written cGy, is one hundredth of a gray, so one gray equals one hundred centigray. Indian centres use both, and some sheets mix them: the prescription may be written in gray while the daily entries are recorded in centigray. If a number on your sheet looks a hundred times too large or too small, this is almost always the reason. Check the unit written at the top of the column before you worry about the figure underneath it.
What should I track on my own copy of the record sheet?
Five things are enough. First, the fraction count written as a fraction, for example twelve of twenty five, so you always know where you are. Second, the cumulative dose against the planned total. Third, any gap, with the date and the reason it happened. Fourth, the dates of your weekly review, your weight check and any blood test, so you can tell whether the routine checks are actually happening. Fifth, a short note on how your skin and your energy are that day. Photograph the sheet at the end of each week. A phone gallery in date order is a perfectly good record.
Can I ask for a copy of my radiation treatment record sheet?
Asking is normal, and centres deal with the request regularly. In general practice at Indian hospitals the treatment record is part of your medical record, and patients or their authorised relatives can request a copy through the medical records desk, sometimes on a written application and sometimes for a small administrative charge. Many teams will simply let you photograph the sheet at the end of a week, which is faster. Ask the front desk or your radiation therapist how their centre prefers to handle it. This page describes general practice and is patient information, not legal advice.
What should I do if an entry on my record sheet looks wrong?
Ask the same day, at the treatment console. Most apparent errors turn out to be a unit difference, an abbreviation, or a correction already made further down the page. Point at the specific line rather than describing it from memory, and ask the radiation therapist or the medical physicist what that entry means. If a session was missed, ask how the schedule will be adjusted and note the answer on your own copy. If you are told a figure is wrong, ask to see the corrected entry rather than accepting a verbal fix. Raising a query about your own record is routine and it will not change how you are cared for.
This page explains, in general terms, how daily radiation treatment records are kept and read at radiotherapy centres in India. Layouts and column names differ between centres. It is patient information, not legal advice, and it is not a substitute for guidance from your own oncology team about your diagnosis, your prescription or your treatment plan.
