分别采用生物辐照仪和模拟铀矿室作为γ 辐照源,研究了低剂量和超低剂量γ 照射对青海弧菌Q67发光强度和光密度(OD_(600) )的影响。实验结果表明,青海弧菌Q67在5.5 cGy /min照射剂量率、不同累积照射剂量γ射线照射下,在一定累积照射剂量范围内,发光强度的抑制率无显著差异,当累积照射剂量超过该范围的累积照射剂量的阈值后,发光强度抑制率与累积照射剂量呈正相关。青海弧菌Q67在320 mGy累积照射剂量,5.5、14和51 cGy /min 3个不同照射剂量率γ 射线照射下,发光强度在低照射剂量率、长时间的γ 射线照射条件下抑制率更大。青海弧菌Q67在长时间超低γ 射线照射剂量率的条件下,菌液的OD_(600)值的...

The effects of low dose and ultra-low dose γ radiation on luminous intensity and optical density (OD_(600) ) of Qinghai Vibrio Q67 were studied using biological irradiator and simulated uranium irradiation chamber as γ radiation source. The results showed that the luminous intensity inhibition rates of Qinghai Vibrio Q67 were no significant difference when the cumulative radiation dose varied within a certain range at a dose rate of 5.5 cGy /min. Once over the dose threshold value in this range,there was a positive correlation between the lum...
