QUSDA WBM SOFTWARE
The software has the following provisions:
a) Registration of the subjects in manual mode or in auto mode
b) Type / reason for monitoring (Routine, Special, Task related, Superannuation monitoring etc).
c) Height and Weight measurement of subject– through BMI machine
d) Subject photo during monitoring
e) Display spectral data as well as CPM for individual detector (1 & 2) and also the summed spectra.
f) Peripheral setting for Auto and Manual mode and their default values
g) Stops monitoring after pre-programmed counting time is over
g) Information about monitored individual’s personal & monitoring history.
k) Estimate intake and committed effective dose (CED) for 137Cs and 60Co following inhalation and / or ingestion
m) Whole Body Counting report generation – two types of reports are generated with flexibility to change the reporting format.
- Generate Go (below threshold level) and No-Go (above the threshold level) report–for operator reference
- Generate monitoring report
