IARC Monographs on the Evaluation of Carcinogenic Risk of Chemicals to Man

a counting bottle caused by other lightproducing processes.' Surely, this 'photon monitoring' is the coincidence counting already discussed in Chap. 3 ? A few minor criticisms: What is an ANS itron counter? (p. 22) The word 'emanation' is used instead of 'emission'. (p. 2) It is suggested (p. 3) that 51Cr can be measured only through its x-ray emission, although Table XIII gives the correct information concerning the radiations emitted by this radionuclide. This reviewer found the section on counting statistics and the use of the E2/B criterion confusing. In the preface, the author expressed the hope that the book will be of value as a textbook for courses, inter alia, in health physics; as this was one of the author's intentions, it is surprising that nothing is said about the problems of disposing of radioactive liquid scintillation solutions, where the dual hazards of radioactive contamination and fire arise. Despite these criticisms, the book does provide a great deal of useful material in a compact and well-produced volume at a price which is modest by current standards.
