likely to interact with matter, a prerequisite for detection. 6. IC electrons are monoenergetic and have much lower energies than electrons ejected from a
nucleus undergoing negatron decay. 7. a) 222 b) None of the radionuclides between 238U and 222Rn are gaseous, so they are much less
likely to be ingested. c) 222
