Radioactive contamination spreads via physical transfer of radioactive particles on skin, clothing, and objects.

The retrieved literature clearly supports the claim that radioactive contamination spreads via physical transfer of particles on skin, clothing, and objects. Papers [0] and [1] both discuss how individuals acquire radioactive particulates on their skin, hair, and clothing, and how these particles can be further transferred via contact or movement to other people or surfaces. There are no papers refuting this well-established physical mechanism.
