  • Title: Chromosome rearrangements from spermatogonial chronic neutron irradiation in mice.
    Author: Bajrakova A, Khadzhieva T, Vasilev G.
    Journal: Mutat Res; 1976 Jan; 34(1):159-62. PubMed ID: 1250246.
    Abstract:
    Adult male mice were given a range of neutron doses at 80 +/- 20 mrad/h from a plutonium-beryllium source. Cytogenetic analysis indicated that chronic spermatogonial exposure to a mean total dose of 10, 30, 52, 98 or 150 rad produced translocations, sampled in spermatocytes four months later, amounting to 0.32, 0.99. 1.69, 1.91 and 1.65%, respectively. The dose response for the 0-52 rad range was linear. For higher doses, a better fit to the data was an expression with dose exponent above unity.
