The oxygen effect, leading to increased radiation damage, can be countered or prevented to a large degree by the addition of 9 atmospheres of argon, nitrogen, or methane to 1 atmosphere of air or oxygen during irradiation. On the other has, the addition of 9 atmospheres of carbon monoxide to 1 atmosphere of air increases the radiation damage. These findings apply to dominant lethals produced in Drosophila virllis and sex-linked recessive lethals produced in Drosophila melanogaster. The stages of spermatogenesis from spermatogonia to mature sperm differ among themselves in their response to the same amount of x radiation and to the oxygen effect and its reduction or enhancement by the other gases.
