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.
The total energy that will be release in a time interval of 3 T 1/2 through alpha decay of the radon-222 is: a. 3.856 MeV b. 5.785 x 10 7 MeV c. 8.677 x 10 7 MeV d. 1.012 x 10 8 MeV e. 1.085 x 10 8 MeV 2. Relevant equations E = mc^2 T 1/2 = (ln 2) / Î» 3. The attempt at a solution
