The setting of long-distance C-type radiation alarm requires comprehensive consideration of installation location, environmental adaptability, equipment performance, safety regulations, and later maintenance. The following are specific setting requirements:
1、 Installation location selection
Away from the radiation source but with effective coverage: The alarm should be installed at a distance from the radiation source, but ensure timely detection of radiation leaks. The installation location should avoid direct radiation to the alarm, while ensuring that the detector can effectively receive any possible radiation.
Avoid interference sources: Avoid installing the alarm near strong electromagnetic fields or sources of electromagnetic interference, such as high-power electronic devices, transformers, etc., to ensure the normal operation and detection accuracy of the equipment.
Easy to maintain and manage: The installation location should be convenient for staff to perform daily maintenance and inspections, in order to promptly identify and address potential issues.
2、 Environmental adaptability requirements
Temperature and humidity control: The temperature and humidity of the installation environment should meet the requirements in the equipment manual, and should usually operate at room temperature and humidity. If the ambient temperature is too high or too low, or the humidity is too high, it will affect the normal operation of the alarm.
Good ventilation: The alarm should be installed in a well ventilated area to avoid equipment damage caused by high temperature or humidity.
Dust and Moisture Protection: In harsh environments, dust and moisture protection for alarms should be considered. If necessary, protective casing can be installed to prevent external factors from affecting the equipment.
Fire safety: The installation area should consider fire safety requirements, especially in areas close to flammable and explosive materials. The equipment should have fire prevention function or be equipped with fire prevention devices.
3、 Equipment performance and configuration
High sensitivity and fast response: The alarm should have high sensitivity, be able to detect trace amounts of type C radiation, and immediately activate the alarm mechanism when the radiation level exceeds the preset threshold. The response time should be as short as possible to ensure that staff can respond quickly.
Multiple alarm methods: The alarm should support multiple alarm methods, such as sound and light alarm, wireless transmission, etc., so as to promptly notify relevant personnel in case of radiation leakage.
Voltage stabilizing power supply and grounding: The alarm should use a voltage stabilizing power supply and install a leakage protection device. The power supply should be independent of other loads to ensure the normal operation of the equipment. At the same time, the alarm must be well grounded to ensure that static electricity accumulation or electrical faults do not affect the equipment.
Cable wiring specifications: Cable wiring should comply with electrical safety standards, and cross cable arrangements should be avoided as much as possible to reduce electromagnetic interference. The cable should be securely fixed to prevent the line from loosening due to vibration or external forces.
4、 Compliance with safety regulations and standards
Compliance with national standards: Ensure that the installation complies with relevant laws and regulations on radiation protection in the country or region, such as the "Regulations on Radiation Safety and Protection Management", "Basic Standards for Radiation Protection", etc.
Follow the manufacturer's requirements: Operate according to the installation manual and technical requirements provided by the equipment manufacturer to ensure that the equipment operates in the best working condition.
5、 Post maintenance and inspection
Regular calibration: To ensure the accuracy of the alarm, it is necessary to calibrate it according to the prescribed time and standards. Because the sensitivity of the alarm may change with prolonged use and environmental changes, regular calibration can keep it in optimal working condition.
Daily inspection and maintenance: Regularly check whether the appearance of the alarm is intact, whether there is damage or corrosion; Check if the connecting wires are loose, disconnected, etc. At the same time, it is necessary to check whether the power supply of the alarm is stable to ensure its normal operation.
Testing and emergency drills: Regular testing should be conducted, especially in situations where there has been no radiation leakage for a long time. Testing can confirm the response capability of equipment by simulating radiation sources. In addition, regular emergency drills should be conducted by simulating actual radiation leakage scenarios to familiarize relevant personnel with the activation and response process of alarms and improve their ability to respond to emergencies.
