NT6101-N50 Environmental Grade X and γ Radiation Dose Rate Meter

The NT6101-N50 environmental monitoring X-ray and gamma radiation air specific release energy (absorbed dose) rate meter uses large-sized NaI (Tl) scintillation crystals as detectors, mainly used for measuring X-ray and gamma air absorbed dose rates in low radiation environments, and searching for radiation sources.

Applicable scenarios

Industrial non-destructive testing: In X-ray or gamma ray testing operations, personnel wear alarm devices to monitor radiation dose, which must comply with the requirements of GBZ128-2002 "Personal Monitoring Specification for Occupational External Exposure".

Nuclear power plant: Staff wear alarm devices to monitor the radiation level around the reactor and waste disposal area, ensuring that the dose does not exceed the safety standards of 50mSv for the age limit and 2.5 μ Sv per day.

Exposure to nuclear environment: Real time monitoring of gamma ray dose in a confined space to prevent acute radiation damage.

Radiation monitoring in radiation rooms and nuclear medicine: When medical staff use alarm devices to monitor the radiation dose around cobalt-60, PET-CT and other equipment, they can use personal dose alarm devices to monitor the X-ray dose in real time and take protective measures. (Note: Non medical devices, only for radiation dose testing)

Nuclear accident emergency: Rescue personnel carry alarm devices into the leakage area, quickly locate high dose points through sound and light alarms, and guide evacuation routes.

Environmental background monitoring: Long term monitoring of natural radiation levels in residential areas around nuclear power plants and establishment of dose databases.
