eli5:What does it mean when an object is irradiated?

646 views

Does this object now also give off radiation/become radioactive?
For example, if a dust particle were to be hit by a ton of gamma radiation, would this piece of dust become radioactive?
Edit: what does it mean when the piece of dust becomes contaminated?

Radtech here, a material is either radioactive or not, and can be made radioactive through intense neutron bombardment to change the overall atomic structure to create an isotope. If a material inherently gives off radiation then it is radioactive, if it is covered by a material that is radioactive then it is contaminated, if it has received a dosage of radiation then it has been irradiated.

If you have received enough neutron radiation to become radioactive then you’re going to have a baaaaad time. I’ve seen what a cobalt-60 source will do to a person… eurgh i’d hate to see neutron.
