WebiMissions Software

Software for collecting and reporting effluent emissions with existing detectors

A cost-effective program, derived from WebiSmarts, for collecting, storing, displaying and reporting effluent emissions from the site using existing detectors. Together with the PM-11 coincidence system it reports only effluent within the exhaust duct and identifies the isotopes. It is intended as an upgrade of existing MediSmarts systems.

Primary function
Collecting, storing, displaying and reporting effluent emissions with existing detectors (derived from WebiSmarts)1
Functions
With the PM-11 coincidence system: reports only effluent within the exhaust duct; identifies F-18, Ga-68, O-15, C-11, N-13, I-131, Tc-99m, Ga-67, Tl-201, I-125 and Lu-1771
