Interaction of γ-ray and Neutron Effects on the Proliferative Capacity of Chinese Hamster Cells

Summary

The loss of reproductive capacity of Chinese hamster cells has been studied using ⁶⁰Co γ-rays and DT neutrons singly or combined in fixed proportions. Surviving fractions were measured down to 2 × 10⁻⁴. Interaction between the effects produced by neutrons and γ-rays in the mixed irradiations has been demonstrated. The results are compared with those predicted by the cellular inactivation model developed by Katz and co-workers from their delta-ray theory of track structure.
