One such example is 241Am, which is. focus on 241Am – source risk (portability, mobility, accessibility, half lives, prevalence (over 10,000 radioactive sources used in oil industry, dangerous alpha  Quantitative measurements of radioactive contamination in the field are For plutonium, the best technique is to detect the accompanying contaminant Am-241 , which Rather, the major potential source of beta and/or gamma emitters is Precautions when Dealing with Equipment Containing Radioactive Sources . 77 241Am α, γ.

The source was found seven hours later in a delivery truck. The package had been intentionally opened. An activity of 1.85 GBq of 60 Co delivers a dose rate of 0.5 mSv/h at a distance of one metre. It appeared that the event was a direct result of failure to comply with the regulations for the transport of radioactive materials:

of carbon, nutrients and point source released radionuclides to an aquatic ecosystem. Americium-241 (241 Am, Am-241) is an isotope of americium.Like all isotopes of americium, it is radioactive, with a half-life of 432.2 years. 241 Am is the most common isotope of americium as well as the most prevalent isotope of americium in nuclear waste. Radionuclide Basics: Americium-241 Americium (chemical symbol Am) is a man-made radioactive metal that is solid under normal conditions.

Americium-241 is formed in the environment by the decay of plutonium contamination from nuclear weapons production and testing. Americium-241 is an unstable isotope. As americium decays, it releases radiation and forms “daughter” elements. Various OSU researchers have gauges manufactured by Troxler or CPN which use 241Am-Be neutron sources in the measurement of soil moisture content.
