The relative biological effectiveness (RBE) of various energy neutrons produced from a Schenkel-type accelerator at the Research Institute for Radiation Biology and Medicine, Hiroshima University (HIRRAC), compared with 60Co gamma-ray radiation was determined and the ratio of the micronucleus induction rates of seed assay to seedling assay by gamma-rays was much lower than that by neutron radiations.

Irradiations of onion seedlings with fission neutrons from bare, Pb-moderated, and Fe-moderated 252Cf sources induced micronuclei in the root-tip cells at similar rates. The rate per cGy averaged for…

Experiments with micro-organisms might add to the possibility of generalising about the change in oxygen enhancement ratio which occurs when the LET of the radiation is changed, this being at the core of the possible advantage envisaged from using fast neutrons in radiotherapy.

Results obtained from cyclotron-accelerated a-particles and deuterons show that in this region the RBE varies rapidly with LET, especially at low levels of damage.

When a meristematic tissue such as that in the root tip of Vicia faba is irradiated, a considerable number of different kinds of change may be induced.

It seemed of interest to investigate the oxygen effect when fast neutrons are used to produce aberrations in Tradescantia, since this radiation is intermediate in effectiveness with respect to chromosome break production between X-rays and alpha particles.

The shape of the curve of RBE against LET for chromosomal aberrations, an effect that may be considered as cellular cytogenetic lethality, is very similar to the curve for a galaxy of mammalian effects including lethality.

Tumor, since it is anoxic, occupies a low position on the oxy-gen-radiosensitivity curve as compared with normal, well vascularized tissue, which stands high on the radiosensitivity curve and, most important, is close to the plateau of maximum sensitivity.
