It's an alpha av A VESTERLUND · 2016 — Neutron sources are constructed in a way that the alpha particle from an alpha-emitting radionuclide such as 241Am or 210Po reacts with a low-Z element, commonly beryllium, and a neutron is emitted from the low-Z element nucleus.

(a) What current… sealed source that is not shielded and encased within the housing of an instrument. Unshielded Am-241 should be used in a well ventilated fume hood or a glove box. Shielding should be used to minimize exposure from Am-241. To help select the source needed, the energies and intensities of the most intense alpha particles emitted by the different nuclides are shown in the table. Selection chart Availability The sources are normally delivered within 4-6 weeks from receipt of order. Radionuclide Alpha particle energy [MeV] Intensity [%] Np-237 4.640 6.2 4.766 8.0 Alpha Source is the exclusive authorized service provider for GE Healthcare BMD equipment parts and the service provider for installation, warranty and post-warranty.

Americium-241 has been used as a portable source of both gamma rays and alpha particles for a number of medical and industrial uses. The 59.5409 keV gamma ray emissions from 241 Am in such sources can be used for indirect analysis of materials in radiography and X-ray fluorescence spectroscopy, as well as for quality control in fixed nuclear density gauges and nuclear densometers . The alpha particles emitted by the Am-241 collide with the oxygen and nitrogen in air within the detector's ionization chamber to produce charged particles (ions). A low-level electric voltage applied across the chamber is used to collect these ions, causing a steady, small electric current to flow between two electrodes. Am-241 found in the environment is in the form of microscopic dust.
