WebRadiation weighting factors. The probability of stochastic radiation effects depends not only on the absorbed dose, but also on the type and energy of the radiation causing the dose. This is considered by weighting the absorbed dose with a factor related to the radiation quality. In the past this factor was known as the quality factor. Web"The 'excited' radiation is of a more penetrating kind than the easily absorbed type (the (x radiation) given out by uranium, but much less than the I8 type. The radiations from radium and polonium are also more readily absorbed in air than the excited radiation is."" 4Rutherford, "Uranium Radiation," pp. 121-122 (CPR, p. 180).
