Atomlab 950 Wipe Test Software

Designed for use with an optional well counter, this program was designed to comply with current government regulations for counting and reporting results of wipes taken in contamination surveys. The program automatically calculates net contamination levels after subtracting measured background activity, and reports results in user-specified units of dpm, µCi, or kBq.

Lower limit of detection (LLD) is automatically determined during the background count. Clicking on the “LLD Estimate” button gives the technician a quick estimate of LLD to determine whether counting times are long enough.

Specific wipe test areas may be named, added to the system database, and edited in much the same way as patient names and

IDs. They may also be designated as “restricted”, “unrestricted”, or “sealed source”. The user enters the isotopes of interest for any specific survey area, and the system counts and reports results accordingly. A detailed spectrum analysis may be performed (on demand) for any specific wipe.

Each designated “area” may include up to ten separate wipe locations (or items) for testing and documenting in that area’s report (i.e. Area Name - “Camera Room”; Location - “counter top”, “table”, “cabinet door”, etc.). A “Wipe Preferences” screen allows the user to specify detector, the detector’s geometric efficiency, default count times, and the activity units to be used in reports.
