TīmeklisWhat are Radium 226 (Ra-226) and Radium 228 (Ra-228)? Radium is a naturally-occurring radioactive metal that is present in the Earth's crust and can be found in plant tissue, animal tissue, soil, and bedrock. Radium is formed in an intermediate step in the radioactive decay series of uranium and thorium which end as a stable isotope of lead.
