This paper is concerned with the problem of difference in dose rate. Are genetic effects the same, or different, when dose rates are widely different, but total dose accumulated the same ? A conventional 124 kv x-ray machine was used for the low dose rate work; an electron beam generator which yielded a rate as high as 5000 r per second was the source of high dose rates. The materials irradiated were Habrobracon oocytes in first meiotic prophase and metaphase stages. These were studied for hatchability or presence of dominant and recessive lethals. F/sub 1/ virgin females were reared from prophase oocytes treated with 12,000 r. These were tested for heterozygosity with respect to recessive lethals. The data so accumulated indicate that with these materials, when total doses of x rays and cathode rays are the same, the wide difference in dose rate has no significant effect. (auth)
