Response of Mammalian Cells Irradiated with 30 MV X-rays in the Presence of a Uniform 20-kilogauss Magnetic Field

Abstract
The effects of intense magnetic fields on the survival curves for aerated and hypoxic Chinese hamster lung cells exposed to 30 megavolt X-rays were investigated. A uniform 20 kgauss magnetic field and a non-uniform magnetic field with an average value of 17.5 kgauss and a gradient of 2.3 kgauss/cm, were employed. A study of the repair of sublethal damage for cells exposed to the magnetic field only during the split-dose irradiations and the effect of exposure to the magnetic field alone for 2 h were also studied. For each of these 4 experiments, no effects attributable to the magnetic field were detected.
