Americium(CAS No 7440-35-9) is the man-made seventh member of the actinoid series. All of its isotopes are radioactive. The most abundant isotope,241Am (half-life 432.2 years), is a gamma and alpha emitter, and has multiple uses. It is present in the environment mainly due to nuclear...
Uses Americium-241 is the only isotope of americium of any practical interest. When it decays, it gives off both alpha rays and gamma rays. Alpha rays do not travel very far in air, but gamma rays are very penetrating, much like X rays. The gamma rays from americium-241 are used in...

A simple to use method was installed for the measurement of wounds contaminated with plutonium and americium by using a semiconductor detector. This technique does not explicitly require the knowledge of the detector efficiency but uses a plant Am-241 calibration source. A computer programme has also...
