Contemporary radiation protection systems (ICRP, 1977a 1991 NCRP, 1987 1993) include dose limits expressed in such a quantity. To obtain the quantity, absorbed doses are first multiplied by a quality factor (ICRP, 1977a) or a radiation weighting factor (ICRP, 1991), selected for the type and energy of the radiation incident upon the body, yielding, respectively, the dose equivalent in the tissue (ICRP, 1977a) or equivalent dose in the tissue (ICRP, 1991). Therefore ... [Pg.2]

For low-LET radiation, the quality factor and radiation weighting factor have the value of one. Therefore, dose equivalent and equivalent dose have the same numerical value. [Pg.2]

Notice that the dose has a strict definition of energy per unit mass of the absorber and, in principle, can be measured for a given radiation at a certain energy in a specific material. The equivalent dose is a relative unit in that a radiation weighting factor is applied to a measured quantity. The dose can be measured from ionization in an electronic radiation detector the equivalent dose must take into account the type of radiation causing the ionization. [Pg.533]

Table 13.3 lists the radiation weighting factors for three types of radiation. [Pg.379]

Note that the radiation weighting factor for alpha particles is 20 times that of gamma rays and f3 particles. With the above information, we can calculate the tissue equivalent dose Hr using ... [Pg.380]
