Non-Hodgkin lymphoma is broadly divided into two major groups: B-cell lymphomas (which develop from abnormal B-lymphocytes, which is most common), and T-cell lymphomas (which develop from abnormal T-lymphocytes). Lymphocytes are a type of white blood cell that helps the body fight infections.
The atomic number of radon (Rn) is 86 and the atomic weight of Rn is 222 grams/mole.
1) Radon-222 gas: - is measured by its activity or rate of decay in units called curies. - One curie equals 3.7 x 10(7) radioactive disintegrations per second. - One pico curie (pCi) equals 3.7 x 10(-2) radioactive disintegrations per sec. 2) Solid radon-222 decay products (primarily polonium 218 and 214).)
