摘　　要：对核电站广泛使用的电缆防火涂料和有机防火堵料进行了耐γ辐射的研究。结果表明:1000kGy以上的γ辐射能严重恶化电缆防火涂料的抗弯性、耐湿热性、耐冷热循环性。500kGy以上的γ辐射对有机防火堵料的耐火性和腐蚀性都有很大影响。In order to guarantee the fire safety of nuclear power plants, we have studied the radio resistance of two kinds of fireproof materials-the cable fireproof coating and organic fireproof putty, which are widely used in nuclear power stations. The results indicate that the γ-ray over 1000 kGy can seriously deteriorates the bending-resistance performance, the wet-resistance and heat-resistance, the cold-resistance and heat-resistance performances of the cable fireproof coating. The γ-ray over 500 kGy not only possess great effects on the corrosion performance of the organic fireproof putty but decreases the fireproof capability greatly.
