Am243
Am243 is an isotope of americium. Americium is a radioactive chemical element with the symbol Am and atomic number 95. It is an actinide metal. Am243 is one of the longer-lived isotopes of americium, with a half-life of approximately 7,370 years. It decays primarily by alpha emission, transforming into neptunium-239. This decay process releases energy, making Am243 a source of alpha radiation.
Am243 is produced in nuclear reactors, typically as a byproduct of plutonium irradiation. It is a significant
While not as commonly used as some other radioisotopes, americium isotopes, including Am243, have found limited
