People exposed to radiations

This may look like a weird question, but can people that have been exposed to Nuclear Radiations, transmit those radiations when in contact with other people?

Like for example if a guy was born and raised in Nagasaki, can this human being transmit radiations?

I should look like the dumbest question poster...

Ah no he can't, unless he had a source of radiation within his body!

If you're just exposed to the radiation, then no you can't pass it on. But if you are contaminated with radioactive material- say fallout dust or through eating contaminated food- then you can. After a nuclear blast or accident there'd be both problems- immediate exposure to the radiation from the blast, and then the contamination from fallout afterwards.

A medical example would be if you have an Xray or CT scan, you are irradiated, exposed to the radiation and can't expose others to it afterwards. But if you have radioactive iodine treatment for your thyroid, you are technically 'contaminated' and you can. They give advice to people having this about what they can and can't do, and for how long afterwards.

And let's think about people that were born and raised in Nagasaki for example after the nuclear war ended.

If those people have radiation sources in the body, the world lets them hanging around the world, or are they quarantined or do they have to pass the scan test to go to other countries?

They don't have sources of radiation in them. This website has some good questions and answers on the situation in. Hiroshima and Nagasaki.

In general no. But there are some really extreme circumstances where it would be possible - these are really ridiculous tho.

For example if you were stuck in a nuclear reactor and bombarded by neutrons then your very crispy corpse (which would actually be vaporised so not a corpse at all) would be highly radioactive.

Neutrons are the type of radiation that can induce this, gamma rays too somewhat. You get hit by neutrons all the time from normal background radiation, which may produce unstable isotopes in your body - insignificantly minute quantites tho.

The control rods extracted from a reactor are radioactive for this reason.
