Routine maintenance
1. Cleaning:
Wipe the monitor's casing regularly with a clean, soft cloth to remove dust and stains.
For detector parts, use specific cleaners or methods according to the manufacturer's guidelines and avoid abrasive materials.
2. Check the battery:
Check the battery level regularly to ensure that the detector can work properly when needed.
If rechargeable batteries are used, they should be charged and maintained according to the manufacturer's recommendations.
3. Protect the detector:
Avoid exposing the detector to extreme temperatures, humidity, or harmful chemicals.
When not in use, the detector should be stored in a dry, clean environment.
4. Check for damage:
Check the tester regularly for any damage, such as cracks, broken connectors, or damaged displays.
If damage is found, it should be stopped immediately and the manufacturer should be contacted for repair or replacement.
calibrate
1. Understand the calibration procedure:
Before performing calibration, read and understand the calibration guidelines provided by the manufacturer.
If you are not sure how to operate, you can contact the manufacturer or professional technicians for guidance.
2. Use standard sources:
Calibration of nuclear radiation detectors usually requires the use of standard sources with known levels and types of radioactivity.
Ensure that the activity of the standard source is within its validity period and has been certified.
3. Calibration steps:
Place the standard source near the detector of the detector at a distance and position as recommended by the manufacturer.
Operate the detector according to manufacturer's guidelines and record readings.
The recorded reading is compared to the expected reading from a standard source, and adjustments may be required if there is a significant difference.
4. Adjustment and verification:
If the reading of the detector does not match the reading of the standard source, adjust according to the manufacturer's guidelines.
Re-measure after adjustment to verify that the reading is close to the expected value of the standard source.
5. Record and report:
Record the date and time of the calibration, the standard source used, the calibration result, and any adjustments made.
In some cases, it may be necessary to report the calibration record to the relevant regulatory authority or quality control department.
Matters needing attention
Calibration and maintenance should only be carried out by properly trained and authorized personnel.
Before performing any maintenance or calibration, ensure that the detector is turned off and in a safe condition.
If you are unsure how to do this, seek professional help to avoid damaging the equipment or causing false tests.
Regular maintenance and calibration ensure the accuracy and reliability of the radiation detector, thus providing accurate data and protection when needed.
