Transferability of ASTM/NIST alanine-polyethylene recipe at ISS

Alanine-polyethylene solid state dosimeters were prepared at Istituto Super iore di Sanita (ISS) following the recipe proposed by National Institute of Standards and Technology (NIST) with the goal of testing its transferabili ty. Dosimeters were prepared using 95% alanine and 5% polyethylene, by weig ht. They are rugged and of increased sensitivity, repeatability and reprodu cibility as respect to the ISS alanine-paraffin pellets. Reproducibility of about 1% was obtained at 10 Gy and at 3 Gy if one single pellet or a stack of five dosimeters were used, respectively. (C) 2000 Elsevier Science Ltd. All rights reserved.
