Hot (Source)

A common 'slang' term used in Health Physics and Radiation Protection to mean something with high levels of radioactivity or Dose Rate. It has no technically recognised meaning and should be used with care since the word can be used subjectively. UK universities commonly use the term 'Hot Lab' to mean a laboratory which contains higher than normal levels of radiation or radioactive material (these labs generally have low levels of activity compared to industry).

The ultimate paradox, of course, is that even though we're all going to die, we've all got to live in the meantime…
