cells could be damaged by absorption of energy of alpha particles. When the dose is great enough, cells are damaged to such extent that they cannot repair themselves. When too great a cell population is affected, thenadverse effectsoccur in that tissue.241Am stays in human and other mammalian...
A white metallic transuranic element of the actinide series, having isotopes with mass numbers from 232 to 247. Am-241 and Am-243 are the isotopes with the longest half-lifes (432.2 years and 7,370 years, respectively), and are alpha-ray and gamma-ray emitters used as radiation sources in...
anion exchange purification of plutoniumthorium oxalateco-precipitationtreatment of radioactive wasteStudies have been carried out on removal of americium from the effluent generated during anion exchange purification of plutonium. Americium 241, generated by the beta decay of Plutonium-241, is the major...

Nearly 98% of the heat is produced through alpha-decay of heavy nuclides, with 244Cm being the main heat emitter with close to 50% of the total power production, followed by 238Pu and 241Am. Concerning neutron source, spontaneous fissions of 244Cm is responsible for 96% of the total ...

The original nucleus is called the parent nucleus, and thenucleus remaining after the decayis called the daughter nucleus. ... If a nucleus emits an alpha particle, it loses two protons and two neutrons; therefore, the daughter nucleus has an atomic mass of 4 less and an atomic number of...
alpha-decaycrystal latticeSamples of Am-241 alloys with gold were synthesized for the first time. The alloys were obtained by the condensation of americium metal vapor on a flat gold substrate. The results of X-ray analysis of the phase composition of the obtained alloys are presented. ...
