This option allows the user to delete a previously recorded count. Highlight the count transaction in the bottom section and select Delete Count.
Manually Adjust Contents
Allows the user to manually specify the amount of activity contained within a bag. Under normal operation the activity within a bag is calculated from the disposals made to it. If however waste was received onto the site this option allows the user to enter the initial activity. It can also be used for low level waste, such as sharps, swabs etc which have not been specifically tied to compounds.
Note it is always advisable to tie all waste, however small, to a compound as this provides a more complete record.
The user must enter the date and time on which the activity is being specified. Then enter the total activity of each radionuclide decay corrected for this date.
The Nominal calculations option recalculates the contents without allowing for decay. This helps calculate contamination radionuclides, as they can then be calculated as a percentage of the nominal/non decay corrected contents.
View Decay Graph
