Two empirical methods of using soils as ionizing radiation dosimeters are presented. These methods were derived through the use of the thermoluminescence characteristics of soils. Method A was designed for irradiated soils for which preirradiation collection of the soils was available. This method is workable for maximum radiation exposure levels up to about 480,000 roentgens. Method B was designed for irradiated soils for which pre-irradiation collection of them was not available. This method is workable for maximum radiation exposure levels up to about 5,000 roentgens. Some of the reasons for the discrepancy in the sensitivity between the two methods are discussed. Various factors that influence the measurement of soil thermoluminescence are discussed also.
