Personal radiation alarm is a portable device used to monitor radioactive rays (such as X, gamma, beta rays) in the environment, mainly used for personal protection in industrial testing, nuclear power plants and other scenarios.
Personal radiation alarm is a portable and wearable radiation monitoring device, mainly used to detect the intensity of ionizing radiation (such as alpha, beta, gamma, X-rays, etc.) in the surrounding environment in real time. When the radiation dose or dose rate exceeds the preset threshold, an alarm is issued to the wearer through sound, light, vibration, and other means to ensure the health and safety of personnel (especially those related to radiation operations).
The core of a personal radiation alarm is a radiation detector, which converts invisible ionizing radiation signals into measurable electrical signals through the detector. After circuit processing and calculation, the signals are displayed in intuitive forms such as dose and dose rate, and the alarm function is achieved.
Main Features
Strong portability: small size (mostly weighing 50-200g), easy to wear, does not affect daily work and movement, suitable for outdoor, on-site and other mobile scenarios.
High real-time performance: continuous monitoring of surrounding radiation levels, real-time data updates, rapid alarm response, and the ability to remind personnel to stay away from radiation sources in a timely manner.
Easy to operate: One click power on, intuitive interface, no need for professional knowledge to master, some support data export (connected to computer via USB or Bluetooth).
Good environmental adaptability: It has the ability to withstand drops, be waterproof, and work in a wide temperature range (-20 ℃~60 ℃), and can operate stably in harsh environments such as nuclear emergency and field exploration.
Low power design: Long standby time, some models support "automatic sleep" function, extending battery life and reducing the trouble of frequent charging/battery replacement.
Precautions for use
Regular calibration: According to regulatory requirements (such as once a year), send it to a professional organization for calibration (such as a metrology institute) to ensure the accuracy of measurement data and avoid false alarms/omissions caused by instrument drift.
Proper wearing: Usually worn on the chest (close to the heart, consistent with the effective dose assessment site of the human body), avoiding blocking the detector (such as metal objects shielding radiation, affecting detection accuracy).
Battery management: When not in use for a long time, the battery should be removed to avoid leaking and damaging the instrument; Check the battery level before work to ensure normal operation in emergency situations.
Avoid accidental triggering: Stay away from strong electromagnetic interference sources (such as high-power motors, microwave ovens), as some instruments may be affected by electromagnetic interference on display; Avoid severe impact on the detector.
Compliant use: Professional personnel must strictly follow the "Regulations on the Safety and Protection of Radioactive Isotopes and Radiation Devices", record the cumulative dose, and not exceed the legal limit.
