The purpose is that the relationships between phase changes of cell cycle induced by heavy ions and dose, repair time are found so as to accumulate necessary basic data for clinical application of cancer therapy with heavy ions.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
Growth delay of transplantable Lewis tumors growing in right hind legs in C57 BI/6J mice were investigated after 12C6+ ion radiation at HIRFL.
