Gamma Watch Detects Radiation

Gamma Watch (Image courtesy GammaWatch.com) By Andrew Liszewski

Given recent events that have gone down in the UK this unique watch from Environmental Instruments Canada Inc. seems rather appropriate. Besides the dated 1980’s-era design the watch also functions as a miniature Geiger counter alerting you when a preset level of radiation has been reached.

If you’re curious as to how the Gamma Watch actually reports the level of radiation then please peruse this paragraph of tech-talk taken from the company’s website. I’m sure it will clear everything up.

The GammaMaster reports dose rate in ?Sv/h and cumulative dose in mSv. If you expose the watch to 1 ?Sv/h for 1 hour, the cumulative dose will be 0.001 mSv. The Sievert (abbreviated Sv) is the internationally accepted unit for equivalent dose. There are 1 000 000 ?Sv and 1 000 mSv in 1 Sv. Historically, the units rem and R have been used. These can be converted to Sv as follows:

1 R ~ 1 rem = 0.01 Sv = 10 mSv = 10 000 ?Sv.

Now I understand!

At the moment the Gamma Watch is sold out but is being replaced by an upgraded model that’s not shipping yet but will be available for about $250.
