Detectors are wipe tested when new, and it is a requirement in many countries that they are re-tested on a regular basis. The frequency of this re-testing is determined by legislation, both national and in-company. Typical periods between wipe testing range from 1 year to 3 years.
Wipe testing involves taking a number of swab samples from the surface of the detector (the number and position depends on the design of the detector). The swabs are then returned to Ellutia, and are tested for any possible radioactive contamination on the surface of the detector. The results are returned to the user for storage and possible examination by regulatory authorities.
Ellutia supplies wipe test kits. Each kit is suitable for testing one detector,the price of the kit includes the cost of testing the wipe samples. These kits contain all the necessary equipment and instruction on how to perform the wipe.
