Abstract:The chlorophyll mutation rate on a large number of plants after the dose rates 0·004–16·800 R/day during the whole vegetation cycle was examined. The mutation frequency increases as early as after the dose rate 4 mR/day. The dose rate of approximately 8 mR/day is necessary to double the mutation frequency.
