GrayQb™ is a cubic device that utilizes multiple layers of Phosphor Storage Plates (PSPs) that are highly sensitive which translates into shorter counting times. Even with low dose rate environments, this device can be used to expedite radioactive contamination cleanup operations. The PSPs from GrayQb™ device are read on a commercially available scanner where special software records and translates the exposure data to define the type and location of the radioactive source(s).

The PSPs used in GrayQb™ are commonly used for imaging purposes where the radiation source and dose rate are known.

Characterizes contamination at a wide range of dose rates (0.01 to over 1000 mGy/hr;1 to over 100,000 mR/hr)
Minimizes exposure to personnel
Able to detect gamma radiation
On-board electronics provides control of the device
Low exposure times due to the high sensitivity of phosphor storage plates
Full 360° coverage in all directions (4p – steradian view).
