Radiation safety after Y-90: what your family needs to know at home | CION Cancer Clinics
After Y-90, the radioactive beads stay in your liver and their radiation reaches only a very short distance, so your family is safe to be near you. For a short time you take simple precautions, mainly around pregnant women and small children. This page explains who needs a little distance, what can carry on as normal, and which symptoms matter far more than radiation. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
Is it safe for my family to be near me after Y-90?
Yes. The radioactive beads stay inside your liver, and their radiation travels only a very short distance, so almost all of it is absorbed by your own body. For a short time afterwards you take a few simple precautions, mainly around pregnant women and small children, and then life at home goes back to normal.
Why the precautions are short
Yttrium-90, the substance inside the beads, loses its radioactivity quickly. Within days most of it has faded, and within a few weeks almost none is left. The beads themselves stay in the liver permanently, but once the radiation has faded they are harmless.
Whose instructions come first
The treating hospital's nuclear medicine team gives you written advice before you leave, and the exact period depends on the dose and the type of bead. Follow their sheet over anything on this page. This page explains the reasons behind the usual advice so the family understands it. If you have not yet had the treatment, read what happens on the day of Y-90 first.
Who in the house
Who needs to keep a little distance, and who does not?
In a joint family, the question is usually about one or two people. Here is how the advice normally divides.
Pregnant women
An unborn baby is the most sensitive to radiation. A pregnant daughter or daughter-in-law should avoid long periods sitting or sleeping close to you during the precaution period. Short conversations across a room are fine.
Babies and young children
Grandchildren can visit and talk to you. For a short time, avoid holding them on your lap for long or letting them sleep beside you. Older children need far less care.
Your spouse and other adults
Ordinary contact, meals together and caring for you are fine. Some hospitals suggest sleeping in a separate bed for a few nights.
Ask your team about sex and intimacy, since advice varies by hospital.You
You cannot harm yourself further at home. Rest, eat well and keep drinking fluids. Do not plan a pregnancy or father a child until your team says it is safe.
Not sure whether this applies to you?
Ask an oncologistThe first days at home
What should my routine look like after Y-90?
Travelling home
Sit apart from any pregnant passenger or small child if you can. On a long bus or train journey from a district, a family member sitting next to you is fine.
The bathroom
Very little radiation leaves your body in urine or stool. Many hospitals still suggest flushing twice, sitting to pass urine and washing your hands well. A shared bathroom is normally fine.
Sleeping
For the first few nights, sleep in your own bed, ideally with a small child or pregnant relative in another room. Everyone else can carry on as usual.
Daily life
Eating together, sharing utensils, cooking and washing clothes need no special care. Visitors can come, though keep long, close visits with pregnant women and babies for later.

Symptoms that need hospital today
Radiation precautions are not the main thing to watch at home. Go to hospital today if you have fever with shivering, severe tummy pain, vomiting blood or black stools, new yellowing of the eyes or skin, new confusion or drowsiness, or swelling or bleeding where the tube went in. Take your discharge letter and say you had Y-90.
Commonly believed
What do families wrongly fear about radiation at home?
"He must live in a separate room for weeks."
Isolation is not needed. A little distance from pregnant women and small children for a short time is the main advice. Keeping someone shut away only adds loneliness to recovery.
"Touching her or eating her food will make us radioactive."
Radiation from the beads cannot be passed on by touch, food, sweat or shared utensils. Nobody in the house becomes radioactive by caring for you.
"The beads stay forever, so the danger stays forever."
The beads stay, but the radiation fades within weeks. After that they are inert and cause no risk to anyone.
"Radiation at home is what causes the tiredness."
Tiredness and a poor appetite come from the treatment working on the liver. See side effects of Y-90 for what is expected.
Being straight with you
What this page cannot tell you
It cannot tell you how many days your own precautions should last. That depends on the dose you were given and the type of bead used, and only the hospital that gave the treatment knows those details. Keep their written sheet somewhere the whole family can read it.
Who this does not apply to
This advice is for Y-90 radioembolisation only. If you had TACE, there is no radioactive material and no radiation precaution at home; read recovery after TACE instead. External radiation such as SBRT also leaves nothing radioactive in the body. Other radioactive treatments, like radioactive iodine, come with different rules.
When to ask again
Ask the treating team before any scan, flight, surgery or hospital visit during the precaution period, and before breastfeeding or trying for a baby. Radiation detectors at airports and some buildings can pick up tiny amounts, so carry your discharge letter when travelling.

Common questions about radiation safety after Y-90
Can I hug my grandchildren after Y-90?
A short hug is fine. What hospitals usually advise against, for a short time, is holding a baby or small child close for long periods, or letting them sleep beside you. Your written discharge sheet gives the exact period. After that, there is no restriction at all.
Can my wife sleep in the same bed?
Many hospitals suggest sleeping apart for the first few nights, mainly as a simple precaution. If she is pregnant, the advice is stricter. Ask the nuclear medicine team at the treating hospital what applies to you, because the advice depends on the dose given.
Is my urine or stool radioactive?
The beads stay locked in the liver, so very little radioactive material leaves in urine or stool. Some hospitals still advise flushing twice and careful handwashing for a short time. Anyone cleaning up vomit or accidents can wear gloves and wash their hands afterwards.
Can I travel back to my district by bus?
Yes, once the treating team has discharged you. Try not to sit beside a pregnant woman or a small child for the whole journey. Carry your discharge letter, which explains the treatment if anyone needs to know, and travel with a relative the first time.
Can I cook for the family?
Yes. Food you cook, plates you use and clothes you wear do not become radioactive. Normal kitchen hygiene is enough. If you feel tired or nauseated in the first days, it is fine to let others take over for a while.
Will an airport scanner detect it?
Sensitive radiation detectors can pick up small amounts for a while after treatment. This is not dangerous, but it can cause questions at security. Carry the discharge letter from the treating hospital, and ask them before booking any flight soon after Y-90.
Can I go back to work?
Radiation is rarely the reason to stay home; tiredness is. Most office work can resume once you feel ready. If your work involves close contact with babies or pregnant women, ask the treating team when it is safe. Read recovery after Y-90 for more.
Who do I call with a question at home?
Radiation questions go to the nuclear medicine team at the treating hospital, whose number is on your discharge sheet. Questions about symptoms, medicines or follow-up can go to your CION oncologist. One CION helpline serves every centre and will put you in touch with the right person.
