An improved in vivo neutron activation system for measuring kidney cadmium
Abstract
An in vivo neutron activation system for measuring kidney cadmium has been redesigned, firstly to reduce ambient dose levels and, secondly, to improve the cadmium signal to neutron dose ratio by modifying the neutron spectrum from 238Pu/Be, by interposing a beryllium premoderator. The ambient dose was reduced by a factor of seven. The overall system performance (lower limit of detection for a given dose) was improved by 40-50%. This 238Pu/Be …
