Can I become contaminated by radiation?

'Radiation' cannot be passed from person to person, just as visible light cannot be passed from person to person.

However, radioactive material (which emits radiation) can pass between individuals in the form of radioactive contamination. Radioactive contamination is a physical substance - and like all substances can move around in the environment. Therefore when considering if it is possible to be contaminated with radioactive material consideration has to be given to its physical properties and environmental factors around it (including possible exposure pathways)

Often in the media the word 'radiation' is used quite carelessly. This extends to ionising and non-ionising radiation which is why mobile phone (e.g. 5G) radiation is often associated with nuclear processes (it is not). So here we are talking about radioactive material which emits ionising radiation.

There are children playing in the street who could solve some of my top problems in physics, because they have modes of sensory perception that I lost long ago.
