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 is a radioactive gas that comes from the natural radioactive decay of radium, which is a natural decay product of uranium.Scientifically, âradonâ is known to be radon-222, the most abundant isotope of the element radon.s a noble gas, radon is colorless, odorless and chemically inert and cannot be detected by human senses. Also, since radon is not chemically reactive with most materials, it will move freely as a gas. Radon has a radiological half-life of 3.8 days, and can move substantial distances from its point of origin.
