Vesting of radiological instruments. An agreement with tite
National Bureau of Standards for the testing of radiation detectionfand
measurement instruments and their component parts has been in operafion
since March, 1951. Since that time O types of radiation detection
vices have been tested.
These tests include experiments such as::chli-
temperature, humidity, shock, and vibration effects. Other relevamt tests
are also initiated when required. The instruments examined to dat@ in~clude special types fabricated in Commission installations, new sa
