Effect of very low doses of gamma radiation on motility of gill ciliated epithelia of Mytilus edulis.
An investigation of the effect of gamma radiation on the motility of mussel gill ciliated epithelia was conducted using dose rates of 0.9 and 2 mGy/h. There was a definite decrease in the beat frequency and a distortion of the metachronal wave by 20-30 min after irradiation with 0.9 Gy/h. With a total dose of 0.9 mGy, the beat frequency was decreased 2- to 2.5-fold. In the period after irradiation a restoration of the metachronal wave was observed, but the beat frequency was about 50% of the control level. Gamma irradiation completely stopped the beating of the cilia when given at a dose rate of 2 mGy/h.
