title: In vivo radiobiology of heavy ions.
abstract: The radiobiology of heavy charged particles has been investigated with various animal systems in vivo at the Lawrence Berkeley Laboratory using the helium beam from the 184" synchrocyclotron and the carbon, neon, and argon beams from the BEVALAC. Tumor experiments were carried out using the R1 sarcoma in rats and the EMT6 mouse mammary carcinoma, comparing X rays, carbon ions, neon ions, and argon ions. In vivo normal tissue experiments have been carried out with a wide range of tissues including testis, bone marrow, intestinal crypt cells, lens of the eye, esophagus, lung, and the spinal cord. The induction of dominant lethal mutations after irradiation of the testis was assayed by in vitro embryo culture after in vivo irradiation. Experiments were also done with the Harderian gland tumor induction system.
