Can I Hold My Child or Grandchild — After a PET-CT Scan?

The waiting period is measured in hours, not days, and the exact time depends on the specific tracer you were given. Your nuclear medicine department will give you this on a printed instruction sheet before you leave. If you did not receive one, or you have lost it, call the department directly — they can give you the correct time for the tracer you received.

Yes. The concern is sustained, close physical contact — a baby held on your lap for a long time, or sleeping together that night. Being in the same room at a normal distance is not what the guidance restricts. You do not need to isolate yourself from your family when you get home.

You do not need to stop permanently, but you need to plan before the scan, not after. Tell your nuclear medicine team you are breastfeeding when you book or check in. They will advise you to pump and set aside or discard milk for a specific period after the tracer is given — the length depends on which tracer was used, so this must come from your team rather than a general guide. If you have already had the scan and forgot to mention it, call the department now.

A brief, unplanned cuddle is very unlikely to have caused harm. The concern is about sustained contact over time, not a single moment. If you are worried, tell your nuclear medicine team exactly what happened — how long and how close — and they can give you a specific answer for your situation rather than a general reassurance.

No. The scan exposes you to radiation from both the tracer and the CT. Your family is only exposed to the small amount of radiation you emit as the tracer decays over the following hours. That is a much lower level, and the guidance is designed to keep it within the limits that India's AERB and international bodies such as the IAEA consider safe for the general public.

The CT is not the concern for your family. That radiation is produced inside the scanner and stops the moment the scan ends. What matters at home is the radioactive tracer given by injection, which continues to decay and emit radiation from inside your body over the following hours. That is what the after-scan precautions are designed to address.

The guidance is most cautious for babies, young children, and pregnant women, because developing tissue is more sensitive to radiation. The same principle applies to older children — limit prolonged close contact during the waiting period — but the concern is lower than with an infant. If your instruction sheet did not specify by age group, call the department and ask.

The main precaution is about physical closeness, not surfaces or food. Washing your hands before preparing food for your child is good practice after any medical procedure. Your child's nappies do not need special handling. If you need to change a baby during the waiting period, do it efficiently and keep the close contact as brief as you can.
