Direct Methods for Measuring Radionuclides in the Human Body

This Safety Practice provides information on the establishment and operation of facilities for the measurement of body activity by direct methods, both in general application and in a range of specific situations. Emphasis is placed on measurements of body radioactivity made in programmes of internal dosimetry for occupationally exposed persons, or in investigations following incidents. Assessments of larger groups following general contamination of the environment are also addressed.
