Abstract

Alanine dosemeters are widely used as solid dosemeters; however, evaluating doses in the mGy order of radiation is difficult because of their lower sensitivity for low doses. We applied the electron spin resonance dosimetry technique to investigate whether hydroxyapatite, the main component of teeth, is a suitable material for a new dosemeter to detect radiation from mGy to Gy. Commercially available synthetic hydroxyapatite possesses the essential characteristics required for a dosemeter material and has been demonstrated to accurately measure doses in the mGy to Gy range.
