Radiac Survey Instrumentation

摘要

This test operations procedure (TOP) prescribes engineering test procedures to determine the technical performance of radiac survey instrumentation. Comparison of test results with technical specifications permits evaluation of their suitability for an intended end use. Modern battlefield conditions have made it necessary that commanders have radiological information concerning contamination of occupied areas. Fall-out predictions provide some information; however, predictions must be confirmed by measurements. Radiacmeters have been developed to fulfill this measurement requirement. This TOP is limited to tests outlined herein, which are applicable to radiacmeters designed for ground and aerial survey. The following tests will measure: (a) Directional Response - The objective of this subtest is to determine the response of the test item to radiation coming from different directions. (b) Accuracy - The objective of this subtest is to determine whether measurements of radiation can be made accurately and repeatedly. (c) Response Time - The objective of this subtest is to determine the ability of radiacmeter to respond to rapidly changing radiation dose rates. (d) Drift - The objective of this subtest is to determine the drift characteristics of the radiacmeter. (e) Warm-up Time - The objective of this subtest is to determine the warm-up time required before the instrumentation can accurately indicate radiation.
