RADIATION METER

Radiation meters, also known as survey meters or radiation detectors, are used to measure and detect various types of radiation, including alpha, beta, and gamma radiation. They are crucial tools in a variety of applications, from monitoring radiation levels in nuclear facilities and hospitals to detecting contamination in the environment. 

Here’s a more detailed overview:
  • Measuring Radiation Levels:

    Radiation meters measure the intensity or dose rate of radiation, providing information about the amount of radiation present in a specific area. 

  • Locating Radioactive Sources:

    They can help pinpoint the location of radioactive sources, either by detecting the presence of radioactive material or by following alarms from other radiation monitoring devices 

  • Evaluating Contamination:

    Radiation meters are used to assess radiation contamination on surfaces, equipment, personnel, or even in the environment

  • Detecting Different Types of Radiation:

    They can be designed to detect specific types of radiation, such as alpha, beta, or gamma radiation, or a combination thereof

  • Applications:
    • Nuclear Power Plants: Monitoring radiation levels in reactors and surrounding areas 
    • Hospitals: Assessing radiation levels in medical imaging and therapy departments 
    • Research Facilities: Measuring radiation levels in laboratories that utilize radioactive materials
    • Environmental Monitoring: Detecting radioactive contamination in the environment 
    • Emergency Response: Localizing radioactive sources and assessing contamination in the aftermath of nuclear incidents 
    • Industrial Applications: Monitoring radiation levels in various industrial processes involving radioactive materials 
    • Radiation Protection: Ensuring the safety of individuals working with radiation sources 

 

 

The Monitor 200 measures alpha, beta, gamma, and x-rays. Its digital display shows readings in your choice of CPM, CPS, μSv/hr, mR/hr, or in accumulated counts. It has a digital, easy to read backlit display, a red count light, and a beeper that sounds with each count detected. This radiation detector device also includes an adjustable timer and a loud, customizable alert.

 

With the Free Radiation Alert Observer BLE app from the Google App Store, you can display the readings from your detector, label sample readings and descriptions, take timed counts, append GPS data and send your saved survey file. Alarms set on the instrument will also activate on your Android device.

The Free Observer USB software (Windows® only) reads in Total Counts, CPM, µR/hr, mR/hr, CPS, µSv/hr, and has the ability to collect and log data, set alarms, set timed counts, set the calibration date and settings, and generate reports.

 Applications & Uses: Checking accelerator & x-ray shielding for leakage, industrial gauges containing Cesium-137, Locating Sources, Personal protection, General surveying

There are many industries that widely use radiation detector device, like medicine, archaeology, agriculture, mining, etc.
