CAPRAC®-R Well/Wipe Counter utilizes a NaI crystal that must be protected for high levels of background or changes in room background activity. This is accomplished by placing the system in a low background area or by using the CAPRAC®-R Auxiliary Shield with walls and top that are .5" thick. Utilizing this extra lead brings the total shielding up to 1". The shield fits snugly around the well chamber and can be easily installed or removed. Capintec suggests using the Auxiliary Shield for all CAPRAC®-Rs.
