calcium41

Calcium-41 is a radioactive isotope of calcium. Its atomic nucleus consists of 20 protons and 21 neutrons. Calcium-41 is a long-lived radionuclide, meaning it decays very slowly. It is primarily produced in the Earth's crust through the neutron capture reaction on calcium-40. Another significant source of calcium-41 is the decay of potassium-41.

The decay of calcium-41 occurs through electron capture, transforming into stable potassium-41. This process releases a neutrino and a gamma ray. The half-life of calcium-41 is approximately 103,000 years, making it a useful tool for dating geological samples and for studying paleoclimates. Its detection and measurement are challenging due to its low natural abundance and low-energy decay products. Research into calcium-41 is important for understanding nuclear physics and for applications in fields such as geochronology and environmental science.
