The GammaWatch Basic is a precision timepiece with a built in solid state radiation detector. The alarm sounds when user defined limits of dose rate or cumulative dose are reached. It is ideal for emergency personnel who may have to respond to 
accidents, incidents or terrorist attacks, which could involve radioactive material. Reasons to have this watch are to identify the presence of nuclear accidents, nuclear or radiological terrorism. By having a radiation meter built into your watch, it is always available. The watch cost $250 will notify you of the presence of radiation, even when you do not think of it. This will be useful in light of the death of Russian dissident Alexander Litvinenko.
