Graetz - Model RadXploreident -Radionuclide Identifier
The GRAETZ RadXplore-ident is an ultra-compact, robust and sensitive radionuclide identifier (RID) that features a wide energy range, high throughput and excellent stability with outstanding application capabilities.
- Most efficient and compact radionuclide identifier on the market
- Easy to use due to intuitive user guidance
- High connectivity and documentation capabilities through interfaces and smartphone app
- Dose rate of almost all radionuclides can be measured due to a very large energy range (10 keV to 1 GeV)
- Very high gamma sensitivity of 1,850 cps/µSv/h (Cs-137)
- Innovative and patented stabilization (Pat. US 9,864,076) based on measurement of the photoelectric quantum effect: no built-in radioactive source or LED required; gain variations are instantly and automatically compensated for
- Ultra-compact design, one-handed operation and waterproof up to 10 meters (protection class IP68)
The RadXplore-ident is designed to detect gamma, beta, neutron and cosmic radiation from natural and man-made sources, identify special nuclear, industrial, medical and natural radioactive sources, and measure X-ray and gamma radiation exposure.
During the development of the device, which is powered by a Li-Ion battery, great emphasis was placed on convenient handling as well as a high degree of user-friendliness. The result is a housing shape and weight that makes the RadXplore-ident highly ergonomic and unique: compact and operable with one hand. This is because, for the first time, it has been possible to combine a 2″ x 1″ BGO (bismuth germanate) detector with high-precision, high-speed digital electronics in an ergonomic, lightweight and waterproof aluminum housing that can be operated with one hand. The RadXplore-ident convinces in use on land, on water and even under water up to 10 meters diving depth.
