目的探讨《放射性肿瘤病因判定标准》修订后,铀矿工肺癌预期数的变化。方法根据GBZ 97-2009及GBZ 97-2002公式倒推95%可信上限病因概率(PC)≥50%和PC≥50%时,铀矿工氡及其子体累积受照剂量水平。结果新标准诊断的矿工肺癌预期数约为旧标准的2倍。结论 GBZ 97-2009有利于患肺癌的铀矿工维权,但是否适合我国国情,仍需推敲。
Objective To investigate the change of expected number of lung cancer in uranium miners after the revision of “Criteria for determining the cause of radioactive tumors”. Methods According to the formula of GBZ 97-2009 and GBZ 97-2002, the radionuclides and their progeny of uranium miners accumulate the dose levels according to the 95% credible causality probability (PC) ≥50% and PC ≥50%. Results The new standard diagnosis of miners expected lung cancer is about 2 times the old standard. Conclusion GBZ 97-2009 is beneficial to the rights of uranium miners suffering from lung cancer, but it still needs to be considered if it suits our national conditions.
