An Analytical Approach to Environmental Radiation Measurements

Environmental radiation measurements have been made and the results reported for the past 15 years. These measurements have included both the neutron and gamma contribution to the environment due to Laboratory operations. In order to determine these values an understanding of the natural environmental radiation must be known. The techniques for measuring environmental gamma radiation have been improved upon during this time and the latest instrumentation and interpretation methods commonly used at this laboratory are reported. Not only is the natural radiation dose rate important but the isotopes responsible need to be identified for a complete understanding of the observed radiation. The techniques for this determination are described.
