A historical perspective is given of the current paradigm that does not explicitly protect nonhuman biota from radiation but instead relies on the concept that if dose limits are set to protect humans, then the environment is automatically protected as well. We summarize recent international questioning of this paradigm and briefly present three frameworks for protecting biota that are being considered by the U.S. Department of Energy, the Canadian Nuclear Safety Commission, and the International Commission on Radiological Protection. We point ...

Radiation sensitizers are agents which can increase the lethal properties of ionizing radiation when administered in conjunction with radiation therapy. They increase radiosensitivity without being innately toxic and give rise to significant increase in the radiation sensitivity of neoplasm over normal tissues. Much laboratory work, mostly in vitro, has shown that many chemical compounds can act as radiation sensitizers. The practicality depends upon the exploitation of the differences between normal and malignant cells when radiation sensitize...

Society's and individuals' concerns about the adverse effects from radiation are logically amplified many times when radiological terrorism is considered. The spectrum of events include industrial sabotage, the use of an explosive or non-explosive radiological dispersal device, the placement of a radiological exposure device in a public facility and the use of an improvised nuclear device. The consequences of an event relate to the physical and medical damage of the event itself, the financial impact, and the acute and long-term medical consequ...

Ultraviolet (UV) irradiation at 254 nm causes different respiration and growth responses in log-phase cultures of Escherichia coli B/r and B(s-1). These differences are correlated with the ability and inability, respectively, of these bacterial strains to repair UV-induced lesions in deoxyribonucleic acid (DNA). After irradiation, B(s-1) cells (radiation-sensitive) exhibit uncoupling of growth and respiration; growth and synthesis cease, whereas respiration continues. B/r cells (radiation-resistant) grown on glycerol exhibit severe temporary in...
