Visualising sources contamination in real time
The RAVIN CAM is a new meter for contamination monitoring in nuclear medicine and imaging departments. What makes it stand apart from conventional methods is the radiation heat map, which the meter overlays on an optical image or live video, allowing sources of contamination to be visualised. This provides a faster and more accurate alternative to Geiger counters and pressurised ion chambers for detecting, locating, and identifying contamination caused by sources of ionising radiation such as 99mTc, 177Lu, and 131I.
Identifying sources of 177Lu and 131I used in therapies
In a study by the University of Michigan, both the RAVIN CAM and a conventional GM counter were used to search for hidden radioactive sources in hot labs, as well as treatment rooms and adjacent bathrooms where 177Lu and 131I MIBG therapies were administered. The study measured the time it took both instruments to detect contamination and compared technical capabilities in locating and identifying isotopes, as well as effectiveness in post-treatment clean-ups.
Detecting residual contamination missed by GM counters
It was found that the RAVIN CAM detected contamination in just 48 seconds, almost three times faster than the GM counter. It also identified the isotope and more importantly, detected residual contamination missed by the GM counter. By being faster and more accurate, the RAVIN CAM allows staff to effectively comply with regulations, as well as safeguard patients and themselves against unnecessary exposure.
