Abstract: Background: The suppression of bacterial luminescence by poisonous substance has being previously reported, such as heavy metals, pesticides, however, rarely radiation. Purpose: This study aims to investigate the toxicity of the bioluminescent bacteria, Vibrio Qinghaiensis sp. Q67, to γ-ray radiation and the possibility of using bacteria as a biological radiation dosemeter. Methods: In this paper, the effects of γ-ray radiation on luminous intensity of Vibrio Qinghaiensis sp. Q67 are studied using 60Co γ radiation source with various dose rate (d) and irradiation time (t). Results: Experimental results show that the relative luminous values (RLV) of Vibrio Qinghaiensis sp. Q67 decrease with the increase of dose rate (d) and irradiation time (t) for acute radiation, and linear bivariate associations is found between RLV and the logarithm value of d and t. Conclusion: Vibrio Qinghaiensis sp. Q67 is sensitive to acute γ-ray radiation, which could be used to monitor γ-ray radiation.

Key words: Vibrio Qinghaiensis sp.Q67, 60Co, Radiation dose, Relative luminous value, OD600
