Abstract

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 (R_LV) 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 R_LV 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
