In this video, the process of conducting a test for a GM (Geiger-Muller) tube and a wipe test is demonstrated. The GM tube is a device used to detect ionising radiation, and the video shows the setup of the GM tube, including the connection of a high voltage supply and the use of a radioactive source for testing purposes.

The video also covers the wipe test, which is used to check for any radioactive leakage on the surface of the radioactive source.  It demonstrates the proper technique for conducting a wipe test. The video emphasises the importance of using appropriate protective measures when handling radioactive materials

Throughout the video, clear visuals and step-by-step instructions are provided to guide physics teachers and laboratory technicians through the process.
