of it. A small piece of americium oxide made with the americium-241 isotope is sealed inside the smoke detector. The americium-241 gives off alpha particles. The alpha particles strike air molecules, causing them to break apart. The pieces formed in this process—ions—are electrically charged...

One application for this property includes making a neutron trigger for nuclear weapons [1, 7]. Polonium Poisoning Polonium is highly toxic [1, 5]. Since it emits alpha particles, exposure to this radioactive element increases the chances of cancer [5]. If inhaled, swallowed, or absorbed ...

It was only in 1940 when Corson, Segre, and MacKenzie at the University of California synthesized the new element by bombarding alpha particles against bismuth. They were unable to conduct further research as the entire focus had to be given to the Manhattan project during the World War 2 for...

Compounds There are no compounds of polonium of practical interest. Some polonium compounds are prepared for the purpose of research. Health effects Polonium is an extremely dangerous substance. When it breaks down, it gives off alpha particles. These particles are tiny, atom-sized particles ...
a massed machine readable medium comprises a machine readable medium with a plurality of particles having resting mass. Specific examples of massed machine readable media can include: non-volatile memory, such as semiconductor memory devices (e.g., Electrically Programmable Read-Only Memory (EPROM),...
