RADIATION SOURCES IN THE ENVIRONMENT

摘要

These experiences underlined the special advantages of the applied method. The determination of environmental radioactivity by in situ gamma spectrometry is fast. Detailed information on the quality and quantity of the component contaminants is provided and a dosimetrically relevant value is obtained for environmental dose rate due to the averaging nature of the measurement. This type of measurement is, however, rather additional than a substitute to the sampling technique, since its estimation for radioactivity concentration in different environmental media are not always accurate enough for further ecological model calculation.
