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.
Index. HyperPhysics ***** Nuclear. Go Back. The decay of radon-222 with emission of an alpha particle is followed within about an hour by a series of four further decays, two of them accompanied by emission of alpha particles and the other two accompanied by other types of radiation.t is part of the natural radioactive decay series starting with uranium-238. It is radioactive with a half-life of 3.8 days, decaying by the emission of alpha particles to polonium, bismuth, and lead in successive steps. Radon is a colorless, odorless gas, a radioactive byproduct of radium.
