The National Metrology Technical Specification JJF 2091-2024, titled "X and gamma radiation personal dose equivalent HP(10) monitoring instrument type evaluation outline," was officially released on January 1, 2024. This document is designed to provide a comprehensive framework for the assessment of X-ray and gamma-ray personal dosimeters that measure dose equivalents at a depth of 10 millimeters in tissue-equivalent material, which is crucial for protecting individuals from excessive radiation exposure during occupational activities or medical procedures involving ionizing radiation.
The specification outlines the necessary performance criteria, calibration methods, testing protocols, and evaluation procedures required to ensure the reliability and accuracy of these monitoring instruments. It addresses key aspects such as instrument stability over time, detection limits, linearity across a wide range of dose rates, energy response, and operational environmental conditions including temperature and humidity variations.
The implementation of this national standard aims to enhance safety measures in various sectors including nuclear power plants, radiological medical practices, industrial radiation applications, and research facilities where exposure to X-ray or gamma radiation is inevitable. By adhering to the guidelines set forth in JJF 2091-2024, manufacturers can produce more dependable personal dosimeters that help protect workers from potential health risks associated with prolonged radiation exposure.
