Abstract

The invention discloses a personal direct-reading ophthalmic crystal dosimeter and a monitoring system thereof. The ophthalmic crystal dosimeter comprises a power module, a high-voltage module, an eye crystal detector and a control system; the control system comprises a single-chip microcomputer, and a timing system, a data storage and reading module, a key control module, an energy spectrum measurement module, a display module, an audible and visual alarm and a computer interface connected with the single chip microcomputer; the monitoring system comprises an ophthalmic crystal dosimeter, and further comprises a computer and an upper management system which are connected with the ophthalmic crystal dosimeter. The personal direct-reading ophthalmic crystal dosimeter can directly perform personal ophthalmic crystal dose direct-reading measurement, and the arranged monitoring system can realize efficient analysis and management of personal eye lens dose measurement data, so that the requirement of performing comprehensive analysis on personnel exposure dose under a new eye lens dose limit value is met.

Description

technical field [0001] The invention relates to the technical field of personal dose monitoring, in particular to a personal direct-reading eye lens dosimeter and a monitoring system thereof. Background technique [0002] The eye lens dose stipulated in the International Basic Safety Standards for Radiation Protection and Radiation Source Safety issued by the International Atomic Energy Agency (IAEA) in 2011 was nearly an order of magnitude lower than the previous limit, which has also been incorporated into the new national standard , which puts forward new requirements for the monitoring and evaluation of eye lens exposure dose in nuclear power plant radiation protection work. [0003] At present, the shortcoming existing in the prior art is as follows: [0004] 1. Eye lens thermoluminescent dose monitoring system: This system can only obtain the dose after the personnel are irradiated by using special equipment to measure and read the thermoluminescent dose tablet in the...
