Abstract : The effect of increasing doses of x rays and of mixed neutron-gamma radiation on the fatty acid synthesizing liver enzyme system in rats has been investigated. It was found that the activity of this enzyme system first increased with radiation dose and then decreased in rats exposed to either x rays or mixed neutron-gamma radiation. Acetyl CoA carboxylase activity was found to be more sensitive to mixed neutron-gamma radiation (decreased) than to x rays, whereas fatty acid synthetase appeared to be more sensitive to x rays (increased) than to mixed neutron-gamma radiation.
