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 naturally occurring radioactive gas. It is produced in the ground through the normal decay of uranium and radium. High radon levels have been found in every state. Dig up the top 6 feet of an acre of land and you will find, on average, about 50 pounds of uranium.
