Puzzled about the distinction between a collective dose of radiation and an absorbed dose? Need to know how cold and epithermal neutrons differ? Don't melt down—flip through this lexicon from California-based company Scientific Digital Visions, which defines more than 1000 terms in nuclear physics, nuclear engineering, and related disciplines. You'll learn that epithermal neutrons pack slightly more energy than cold neutrons. And an absorbed dose refers to the quantity of radiation received by a given amount of material, whereas a collective dose indicates the total accumulated by a population over a certain period.
