To download a video of the unit responding to radiation, right click here and select "Save Target As..." in Internet Explorer or "Save Link As" in Netscape. This is a 2.3 Meg file and takes about 10 minutes over a dialup connection.

If you have a fast connection, right click here. This is the same video with slightly better resolution (4.4 Meg file).

The videos are 56 seconds long and show how the watch responds when a radioactive source (a radium dial watch) is brought close to it. The radium dial produces about 10 µSv/h and the GammaMaster responds to it within a few seconds.

If the video you are seeing is shorter than 56 seconds, please try your download again. (Sometimes only the first 10 or 15 seconds download.)
