title: Relation between the weight of human tooth enamel and the CO3(3-) signal intensity on the ESR dosimetry.
abstract: Experiments were made to determine the dependence of CO3(3-) signal intensity on enamel weight in the ESR dosimetry utilizing teeth. After all human tooth enamel samples were crushed into 500-840 micrometers particles, they were irradiated with various doses of 60Co gamma rays at the same dose rate. Irradiated samples were distributed into 10-500 milli-grams weights and were measured with ESR instrument. The relation between CO3(3-) signal intensity and enamel weight have linearity up to 300 mg weight under the same dose as shown by measurements.
