Nuclear Medicine Physics CourseLaboratory 5Area Wipe TestWhat we will doPerform a set of weekly wipe tests and surveys of working environmenttests for integrity and cleanliness. These instructions are general and describe one way of getting the job done. During On the home page of the system select “weekly wipe” test.Select “area wipe tests” and check off the areas for which you took wipes.Place one test tube with clean swab into the well counter and cover the well and take a background count (1 minute). (Expect background to be about 100 200 counts for a 1minute count time.) Accept the background and press count for the next wipe.When the system tells you to insert a specific wipe, insert the corresponding test tube, then press OK. When the system stops counting accept the count and repeat procedure for all wipes.When done exit the page and print the report for all the wipes.Compare the results with permit
