Monitoring for Internal Contamination of Nuclear Energy Personnel

Abstract

Measurement and control of doses received from external radioactive sources has for several years been performed by means of some type of integrating dose meter, which can be attached to the individuals. The technique normally used is suitable for routine treatment as is the evaluation and handling of the results. A similar method for measuring and control (monitoring) of internal contamination does not yet exist. Use of sensitive individual dose meters e.g. thermo-luminescence-meters, for recording exposure from internally deposited radioactivity when the individual is away from abnormal high external radiation, has not been reported. This technique perhaps deserves some attention due to the potential merits of simplicity and economy.
