Dose-damage relationship methods

The first category can be dealt with by straightforward reference to the economic costs of repair, although the actual calculation is by no means straightforward as dose/response relationships depend upon the depth of corrosion that has taken place, climate, local building materials, construction methods, etc. Nevertheless attempts to estimate building damage costs have been made. 

Neutron dosimetry by foil activation is not used so much to record doses received by personnel as it is to record doses to materials, instruments, or other components that may suffer radiation damage as a result of neutron bombardment. The principle of this method was presented in Secs. 14.4 and 14.6. A target, in the form of a thin small foil, is exposed to the neutron field and becomes radioactive. The relationship between activity and neutron flux is... 

Pleochroic haloes have been used to date minerals and rocks. The method depends on the fact that the intensity of their colors increases with the alpha dose to which they have been exposed. The relationship between the two may fall into any one of three categories. In the first place, a normal stage exists in which color increases linearly with radiation dose. Secondly, there is a saturated stage in which the color reaches a maximum density and does not show any further increase with increasing radiation dose. Thirdly, there is an inversion stage in which coloration actually decreases with the intensity of the radiation dose - this is caused by extreme radiation damage. Only those from the first category are used for age determinations.
