X. Gamma personal dose alarm device

X. The gamma personal radiation alarm is commonly used in radiation protection training in medical institutions. By simulating operational practices in different radiation scenarios, medical staff can intuitively perceive radiation threats, enhance their awareness of radiation protection, and improve their ability to respond to radiation emergencies.

1、 Product Introduction:

LJ-2000 typeX. Gamma personal dose alarm deviceIt is an instrument for monitoring personal radiation dose for personnel who come into contact with radioactive isotopes or radiation devices. This instrument can simultaneously measure dose equivalent rate and dose equivalent, and users can set their own alarm threshold (threshold value) for dose equivalent rate according to their needs.

The instrument adopts advanced energy compensation technology and has good accuracy in measuring rays of different energies.

Compliant with standard: GB/T 13161-2015 "Radiation Protection Instruments for Measuring Personal Dose Equivalents Hp (10) and Hp (0.07) for X, γ, Neutron, and β Radiation".

2、 Application areas:

Hospital imaging department, nuclear medicine department, dental clinic;

Disease control and health supervision agencies;

Homeland security, customs, border inspection ports, universities and research institutes;

Emergency fire personal radiation monitoring;

Environmental radiation monitoring, nuclear emergency sites;

Industrial X, gamma non-destructive testing;

Third party testing companies;

Abandoned metal processing plants, mines, oil fields, etc.

3、 Functional features:
