Abstract

The author reviews some of the methods and instruments developed at Harwell Laboratory for monitoring airborne particulate activity in (1) ducts and stacks which might carry radioactive aerial effluents; (2) working areas within nuclear facilities where a hazard from airborne radioactivity might exist; and (3) the breathing zones of individuals who might be exposed. Instruments for both real-time and retrospective measurements are described. Particular attention is given to instruments using alpha spectrometry and individual compensation against each radon and thoron daughter; discrimination by decay rate; extended-range monitors and combined alpha beta monitors
