Abstract:
Objective To complete the Monte Carlo design and preliminary test of X-ray protective rubber. Methods According to the characteristics of X-ray energy spectrum for interventional therapy, the shielding effects of lead rubber, tungsten and bismuth composite rubber, and gadolinium and bismuth composite rubber samples were calculated by Monte Carlo simulation. The variation law of lead equivalent of lead-free rubber and lead rubber with X-ray peak tube voltage was obtained through actual measurement. Results Within the peak tube voltage range of 60-110 kV, lead-free rubber effectively replaced lead rubber. Conclusion The shielding and attenuation effect of the existing lead-free protective rubber on low-energy stray X-rays is better than that of lead rubber. Considering the inherent defects of lead rubber, flexible X-ray protective materials with thermoplastic elastomer as filler will have broad development prospects.
