NM01RJ311155

The RJ31-1155 is a personal dose alarm meter designed to measure and monitor exposure to X-rays, gamma rays (Y), and hard beta particles (hard-β). It is manufactured by Raytech and is designed to provide real-time monitoring and alarms to protect individuals working in environments with potential radiation hazards.

Key Features and Specifications:

• Radiation Types:

  • Measures X-rays, gamma rays (Y), and hard beta particles (hard-β).

• Dose Rate Range:

  • 0.01 µSv/h to 150 mSv/h (microsieverts per hour to millisieverts per hour). This indicates the range of radiation intensity the device can measure.

• Cumulative Dose Range:

  • 0.00 µSv to 9999 mSv (microsieverts to millisieverts). This indicates the total accumulated radiation dose the device can track.

• Energy Range:

  • 40 keV to 3.0 MeV (kiloelectron volts to megaelectron volts). This specifies the range of radiation energy the device can detect.

• Manufacturer:

  • Raytech.

• Personal Dose Alarm:

  • The device is designed to alarm the user when a preset dose rate or cumulative dose is reached.

Applications:

• Nuclear power plants.

• Medical facilities (radiology departments).

• Industrial radiography.

• Research laboratories.

• Any environment where individuals may be exposed to ionizing radiation.
