Baoying County Hospital Civil Air Defense Type C Radiation Alarm

1、 Product Overview

Type C radiation alarm is a specialized device used to monitor type C radiation in the environment（γIntelligent safety detection equipment for radiation intensity. This device is based on high-sensitivity radiation detection technology and can perceive in real timeγWhen the radiation dose rate changes and the detection value exceeds the preset threshold, users are immediately reminded to take protective measures through sound and light alarms, which are widely used in the nuclear industry, medical radiology, geological exploration, environmental monitoring, customs inspection, and scientific research laboratoriesγPlaces with radiation risks are important equipment for ensuring personnel radiation safety and environmental radiation monitoring.Baoying County Hospital Civil Air Defense Type C Radiation Alarm

2、 Core functions

1. Real time monitoring functionUsing high-precision scintillation crystal detectors or semiconductor detectors, it can continuously and real-time collect data in the environmentγThe radiation signal is converted into quantifiable dose rate data (usually in units of)μSv/hormSv/h）Ensure 24/7 monitoring of dynamic changes in radiation levels.

2. Sound and light alarm functionBuilt in buzzer and high brightnessLEDAlarm light, when detectedγWhen the radiation dose rate reaches or exceeds the preset alarm threshold (supporting users to customize high and low thresholds according to actual needs), the device immediately starts the sound and light alarm, with sound intensity≥85dB(Distance)1At a distance of meters, the flashing frequency of the light≥2HzEnsure effective reminders even in noisy environments.

3. Data display functionEquipped with high-definition technologyLCDorOLEDDisplay screen, capable of real-time display of the current situationγKey information such as radiation dose rate, cumulative dose, alarm threshold, equipment working status (normal, alarm, fault), and battery level, displaying data update cycle≤1Seconds, clear and intuitive reading.

4. Threshold setting functionSupport users to flexibly set the alarm threshold through device buttons or supporting software, meeting the radiation safety standards requirements of different places (such as public areas, control areas, and supervision areas), while also having threshold locking function to prevent unauthorized personnel from misoperation.

5. Data recording and storage functionBuilt in storage chip that can automatically record the time and location of alarm events (if equipped)GPSThe storage capacity for information such as modules, radiation values, etc. shall not be less than10Ten thousand records, supported throughUSBInterface or wireless transmission (BluetoothWi-Fi）Export data in a way that facilitates subsequent data analysis and traceability.

6. Low battery alarm and automatic shutdown functionWhen the battery level of the device is lower than the preset value, it will automatically emit a low battery warning sound and display it on the screen to avoid monitoring interruption caused by battery depletion; If the device is not operated for a long time or the battery level is extremely low, it will automatically shut down to protect the battery.
