K-band EPR dosimetry: small-field beam profile determination with miniature alanine dosimeter
The use of small-size alanine dosimeters presents a challenge because the signal intensity
is less than the spectrometer sensitivity. K-band (24GHz) EPR spectrometer seems to be a
good compromise between size and sensitivity of the sample. Miniature alanine pellets were
evaluated for small-field radiation dosimetry. Dosimeters of DL-alanine/PVC with
dimensions of 1.5 mm diameter and 2.5 mm length with 5mg mass were developed. These
dosimeters were irradiated with 10MV X-rays in the dose range 0.05–60Gy and the first …
