Personal direct-reading acra dosimeter and monitoring system thereof

Abstract

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

Description

technical field [0001] The invention relates to the technical field of personal dose monitoring, in particular to a personal direct-reading extremity dosimeter and a monitoring system thereof. Background technique [0002] In accordance with the national standard "GB18871-2002 Basic Standards for Ionizing Radiation Protection and Radiation Source Safety", the limit value requirements for hand and foot doses of exposed personnel are required. In addition, in the field of radiation protection, there is a requirement of "optimization of radiation protection", which requires that after considering economic and social factors, the size of the personal exposure dose, the number of people exposed, and the possibility of exposure are all kept at a reasonably achievable level. as low as possible. In the past, in the implementation of radiation protection optimization, the exposure dose was often only concerned with the individual effective dose. In recent years, the IAEA pointed ou...
