Abstract: | 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. |
