Abstract

The invention relates to a multi-parameter measurement system for testing the environmental adaptability of a radiation dosimeter, and belongs to the technical field of environmental adaptability and reliability tests. The system comprises a temperature and humidity test box and a portable ray irradiation device mounted on a high-precision positioning rack, wherein a to-be-tested instrument is located on the central axis of a ray reference radiation field generated by the portable ray irradiation device and is a set distance away from the portable ray irradiation device, and theto-be-tested instrument and a fixing mechanism are arranged in the temperature and humidity test box. The measurement system provided by the invention can realize radiation performance parameter test of the nuclear radiation dosimeter under complex environmental conditions, and improves the environmental adaptability and reliability of the radiation dosimeter.

Description

technical field [0001] The invention belongs to the technical field of environmental adaptability and reliability testing, in particular to a multi-parameter measurement system for environmental adaptability testing of radiation dosimeters. Background technique [0002] Environmental suitability and reliability are both important quality characteristics of a product. Environmental adaptability is the ability of equipment or products to realize all their functions and performances without being damaged under the action of various environments that are expected to be encountered during storage, transportation and use during its life cycle. Reliability refers to the ability of the product to complete the specified functions under specified conditions and within the specified time. The reliability of the product is closely related to the stress state of the external environment and the demand for product functions. [0003] With the wide application of nuclear science and techn...
