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.
Dose: 200 mrem per year. Radon is a radioactive gas that you canât see or smell, but it may be in your home. It often creeps in through the floor or walls from natural decay of uranium in the ground, and gets trapped within the building; it can also be present in construction materials.
