ENVIRONMENTAL RADIATION: MEASUREMENTS OF DOSE RATES.

The exposure dose from environmental sources of radiation was determined by means of an ionization chamber, by gamma-ray spectrometry in the field, and by measurements of radioactivity in soil cores. The exposure dose from cosmic radiation was found to be 4.4 +/- 0.2 micror/hr, that from natural radioactivity 8.0 +/- 0.3 micror/hr, and the contribution from fission products varied from 2.0 to 7.5 micror/hr during the interval in question.
