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.
Radon -222 is a gas produced by the decay of radium -226. Both are a part of the natural uranium decay chain. Uranium is found in soil throughout the world in varying concentrations. Among non-smokers, radon is the largest cause of lung cancer and, overall, the second-leading cause.
