Preparing a Child for the Radiation Mask and Machine — A Parent’s Play-First Guide
Many children can be prepared to lie still for radiation without daily anaesthesia. It takes an honest explanation pitched at their age, a walk through the treatment room before day one, and about a week of play practice at home. Here is what to say, what to show and what to rehearse.
Medically reviewed by Dr. Venkata Sushma P, Radiation Oncologist, MBBS · MD (Radiation Oncology) · Last reviewed August 2026
- Explain it in their words — an age-by-age script for toddlers, school-age children, pre-teens and teenagers, so you are not improvising the night before the planning scan
- Yes, they can see the room first — a room walk-through, a mask-making session and a full no-beam rehearsal are standard requests in paediatric radiotherapy — ask for all three while the plan is still being made
- Play practice can avoid daily anaesthesia — a home-made mask, a statue game against a timer and a rehearsed goodbye at the door turn “lie completely still” into something your child has already done
- One team, one coordinated plan — your child’s radiotherapy is delivered at an NABH-accredited partner centre; CION Cancer Clinics coordinates the treatment plan, the oncology team and the follow-up throughout

The direct answer
How Do I Explain the Radiation Mask to My Child?
Tell the truth, in their words. The mask is a sheet of plastic mesh that is warmed until it goes soft, moulded over the face or head, then left to harden. On treatment days it clicks onto the bed so the head cannot move. It does not hurt. The machine hums and moves around them, and nobody stays in the room, but you can see and hear each other throughout.
Use the real words early. Children who are told “it is just a photo” and then meet a mask that clamps to a bed lose trust on day one, and that trust is what you need for the next twenty-five sessions. Say the word mask. Say the word machine. Say that it is not a punishment and that nothing they did caused it.
Name the two things children actually fear. Not radiation. Being alone in the room, and being held down. Answer both before your child has to ask: you will be right outside a door they can point to, and the mask holds their head rather than someone holding them.
Do not promise it will be quick if you do not know yet. A course may run every weekday for several weeks. Promising “only a few days” and being wrong costs more than the honest answer. Give the number of sessions once the plan is confirmed, and mark them on a calendar your child can cross off.
Say it in the language your child thinks in. If home runs in Telugu, explain it in Telugu, even if the appointment happened in English. Our team can go through the whole conversation with you in Telugu, Hindi or English, so you are using the same words at home that the centre used in the room.
| Age | What to call it | What to say about the mask | What they most need to hear |
|---|---|---|---|
| 2–5 years | The special bed that takes pictures | “A warm, wet net goes on your face like a superhero mask, then it gets hard and holds your head still.” | Amma or Nanna is just outside that door and comes back the moment the beeping stops. |
| 6–9 years | The treatment machine | “The mesh is shaped to your face so the treatment lands in exactly the same spot every single day.” | It does not hurt, and you will not feel anything at all while the machine is switched on. |
| 10–13 years | Radiotherapy — use the real word | “The mask holds your head to within a millimetre, so the healthy parts around the target get as little as possible.” | You are not helpless: you can talk to the team on the intercom, and they can stop the machine. |
| 14–18 years | Full clinical names for everything | Ask to see the planning images and to hold the mask before it is fitted. Teenagers cope far better with detail than with reassurance. | Your questions about school, sport, hair, fertility and the years after treatment are legitimate. Ask them now, not later. |
One sentence to avoid: “it will not be scary.” If it turns out to be frightening, your child concludes you did not know or were not telling the truth. “It is hard, and you can do hard things, and I will be right there” survives contact with the actual room. The same goes for anaesthesia — never promise your child they will be awake, or asleep, before the team has decided.
Did you know?
Age is the biggest single factor in whether a child needs daily general anaesthesia for radiotherapy. Children under about three almost always need it, while many children from roughly age four upward can be prepared to lie still awake. Structured play preparation, a room visit and a rehearsal on the treatment bed are the standard tools paediatric radiotherapy teams use to get there — which is why they are offered before the first session, not after a difficult one. (Paediatric radiotherapy patient guidance, ASTRO and SIOP; as of August 2026.)
Before day one
Can My Child See the Radiation Room and the Machine First?
Yes, and you should ask for it. A walk through the treatment room with nothing switched on, a mask-making session, and a rehearsal on the treatment bed with no beam are standard requests in paediatric radiotherapy. Ask while the plan is still being made, not on the morning of the first session, because each one has to be booked into the schedule.
Ask for this · 1
The room walk-through
Ten quiet minutes in the treatment room with the machine off. Let your child touch the bed, look at the lights on the ceiling, find the camera and the speaker, and see the door you will be standing behind. The room is large and cold, and that surprise is worth spending on a day when nothing else is happening.
Ask for this · 2
The mask-making session
The mesh is warmed in water, laid over the face and smoothed down, and hardens in a few minutes. It feels like a warm wet cloth, then tight. Openings are left for breathing, and the eye and nose areas can usually be enlarged if your child finds the covering hard. This happens at the planning scan, before any treatment.
Ask for this · 3
The no-beam rehearsal
A full dry run: onto the bed, mask on, lights lined up, everyone leaves, the machine moves, nothing is switched on. If your child can complete this once, the first real session is a repeat rather than a first. If they cannot, the team has learned something useful with no treatment time lost.
Then every day
The daily routine
Most of the appointment is set-up, not treatment. Expect roughly ten to twenty minutes in the room, of which only a few minutes are beam-on. Same time slot, same parent at the door, same soft toy, same words. Sameness is the single strongest thing you can offer a child over a multi-week course.
Where this happens. Your child’s radiotherapy is delivered at an NABH-accredited partner centre; CION Cancer Clinics coordinates your treatment plan, your oncology team and your care throughout. That includes booking the room visit, the mask fitting and the rehearsal, and making sure the paediatric anaesthetist is part of the conversation from the start rather than after a difficult first day. Call our care team on 1800 202 8726 to ask for any of the three.

Your Child Should Meet the Machine Before It Meets Them
Ask us about a room walk-through, a mask-making session and a no-beam rehearsal before day one. We coordinate all three with the partner centre where your child is treated.
The part that changes the day
What Play Preparation Actually Helps a Child Lie Still?
Rehearse the exact thing you are asking for. Lying flat on the back, arms at the sides, face covered, completely still, for longer each day across the week before treatment starts. Turn it into a game with a home-made mask, a timer and a sticker chart, and many children manage the real thing awake.
1
Make a pretend mask at home
A clean plastic strainer, a mesh colander or a cardboard frame with a cut-out face is enough. Put it on a doll or a soft toy first, then on you, then on your child. Let them decorate it. The point is that a covered face becomes familiar in your own home, days before anyone at a hospital asks for it.
2
Play the statue game against a timer
Flat on the back, arms by the sides, chin gently up, absolutely still. Start at thirty seconds. Add a little each day and aim to reach the length of time your team says your child will be on the bed. Let your child hold the timer and set the target — children who choose the number stick to it far better.
3
Rehearse the part where you leave
This is the step most families skip and the one that most often causes tears on day one. Play the statue game while you step out of the room, talking the whole time through a phone on speaker. Come back the second the timer stops, every time, so leaving and returning become one predictable unit.
4
Choose the sound before you need it
Most treatment rooms can play a song, a story or a recording through the speakers. Pick it at home during the practice sessions, so the same track is already tied to lying still. A parent’s recorded voice counting down works well for younger children who cannot yet follow a story.
5
Let them own the real mask
Many centres allow a sticker, a drawn-on face or a chosen colour on the immobilisation mask — ask before you bring anything, since nothing can be added that changes how it fits. A mask that belongs to your child is a very different object from one that is done to them.
6
Build a visible countdown
One sticker per session on a chart, with the final day marked and named. Small daily rewards work better than one large promise at the end, because a multi-week course is far longer than most children can hold in view. Siblings can be given a job in the chart too.
7
Keep every other variable the same
Same appointment slot, same parent at the handover door, same soft toy, same sentence as they go in. Novelty costs a frightened child far more than it costs an adult. If something has to change, tell them the evening before rather than in the corridor.

If awake is not possible
What If My Child Still Needs Anaesthesia Every Day?
Then they have it, and that is not a failure of preparation. Children under about three almost always need daily general anaesthesia so they stay completely still, and some older children do too. It is given by a paediatric anaesthetist every weekday of the course, with a strict fasting window before each session.
The decision is made together, after a trial
the paediatric anaesthetist and the radiation oncologist decide jointly, usually after a rehearsal, rather than on the first morning
Get the fasting hours in writing
separate windows usually apply to solid food, to milk and to clear fluids — ask for the exact hours for your child’s slot, because a missed rule cancels the session
Ask for risk as a range, not a reassurance
ask the anaesthetist to state the risk of repeated short anaesthesia as a range for your child’s age and health, and to say plainly what is still under review for the youngest children
It can often be stepped down mid-course
some children start asleep and move to awake sessions once the routine is familiar — ask for that to be reviewed weekly rather than assumed fixed for the whole course
Plan the day, not just the session
a fasted, sleepy child needs a settled first meal, a quiet hour and a realistic school plan afterwards — the appointment is not the whole of the day
Ask for the follow-up plan before the last session
radiation to a growing child can affect growth, hormones and other tissues years later, depending on the site and the dose — surveillance is planned from the start, not arranged later
Never skip or delay a session on your own because the morning went badly. Gaps in a radiation course can affect how well the treatment works. Call the team instead and say plainly what happened — a changed time slot, an added rehearsal, a different handover routine or a review of anaesthesia often solves it. Any change to the schedule, and any decision about sedation, belongs to your child’s treating doctors after a proper conversation with you. Reach our care team on 1800 202 8726.

Common questions
Preparing a Child for the Radiation Mask — Parents’ Questions
How do I explain the radiation mask to my child?
Tell the truth in their words. The mask is a sheet of plastic mesh that is warmed until it goes soft and floppy, moulded over the face or head, then left to harden. On treatment days it clicks onto the bed so the head cannot move. It does not hurt. Say the machine hums and moves around them, that nobody can stay in the room while it is on, and that you can see and hear each other the whole time on camera and intercom. Use the real words with children over about eight. Say it in the language your child is most comfortable in, whether that is Telugu, Hindi or English.
Can my child see the radiation room and the machine before treatment starts?
Yes, and you should ask for it. A walk through the treatment room with nothing switched on, a mask-making session, and a full rehearsal on the treatment bed with no beam are standard requests in paediatric radiotherapy. Ask for all three while the plan is still being made rather than on the morning of the first session, because they need to be booked into the schedule. Seeing the room first is one of the most reliable ways to make the first real session ordinary rather than frightening. CION Cancer Clinics coordinates these visits with the partner centre where your child is treated.
What play preparation helps a child lie still for radiation?
Practise the exact thing you are asking for. Make a pretend mask at home from a clean plastic strainer or a cardboard frame, let your child decorate it, and try it on a doll or a soft toy first. Then play a statue game lying flat on the back, arms by the side, against a timer, starting at thirty seconds and building over a week towards the real time on the bed. Rehearse the alone part by stepping out of the room while talking through a phone on speaker. Choose a song or story to be played in the room. Add a sticker chart with one sticker per session.
Will my child need general anaesthesia for radiation therapy?
It depends mostly on age and temperament. Children under about three years almost always need daily general anaesthesia so they stay completely still, and some older children need it too. Many children from around four upward can be prepared to lie still awake, which is exactly what play preparation and a room rehearsal are for. The decision is made together by the paediatric anaesthetist and the radiation oncologist after a trial run, not on day one, and it can be reviewed during the course. Ask for the risks of repeated short anaesthesia to be explained as a range specific to your child, not as a general reassurance.
Does the mask hurt, and can my child breathe and see through it?
The mask does not hurt. The mesh is warm and damp when it is moulded, which most children describe as feeling like a warm wet cloth on the face, and it cools and hardens in a few minutes. It has openings so your child can breathe normally, and holes for the eyes and nose can usually be enlarged if your child finds the covering difficult. Tell your child in advance that it will feel tight and close, because the tightness is the part that surprises children who were told only that it would be fine. If your child panics with the face covered, say so before the mask is made.
Where does my child's radiation actually happen, and who looks after them afterwards?
Your child's radiotherapy is delivered at an NABH-accredited partner centre; CION Cancer Clinics coordinates your treatment plan, your oncology team and your care throughout. That coordination covers the planning scan, the mask fitting, the daily schedule, anaesthesia if it is needed, and the follow-up afterwards. Radiation to a growing child can affect growth, hormones and other tissues years later, depending on the site treated and the dose, which is why paediatric survivorship guidance asks for lifelong surveillance planned from the start rather than arranged later. Ask for that follow-up plan in writing before the last session, not after it.
