The system consisted of 3 boards of rice seeds (1# and 2# for Qinghua non-glutinous rice and 3# for Pearl early rice, Huiyang) and 10 layers of solid state nuclear track detectors (CR-39) in sandwich (Fig.1). It was loaded in space shuttle Shenzhou 3 (at astronaut seat) in the last 10-day period of March, 2002.展开更多

The radiatioa detector is cheap and easy to handle. The radiation inducing free radicals are stable at normal laboratory conditions for doses below 10^4 Gy over a long period of time, which makes the detector useful for intercomparison and documentation purposes. The dosimetric features of alanine-based electron spin resonance (ESR) detectors in high energy electron beams used in radiotherapy were considered[2]. The 5 mm long alanine detectors were found to be the most suitable for carrying out in vivo dosimetry on patients undergoing electron beam radiotherapy. However, data concerning dosimetry of the alanine dosemeter to heavy charged particles are lacking, especially in China.展开更多
