“…After removal of the radiation source, the avoidance continued for a while in all but the monkeys which began immediately to drink from the previously avoided water container. Conditioned spatial avoidance was observed in rats by Garcia, Kimeldorf, and Hunt (1957) and by Overall et al, 1959). Garcia et al (1961) demonstrated spatial avoidance as a result of very brief exposures to x-rays, to supplement previous findings involving x-and gamma-radiation exposures of an hour or more.…”

“…© 1999 Academic Press Conditioned preference and aversion tasks have been widely used in studies of nonhuman species to elucidate the neural substrates that mediate reward and aversion, as well as the cognitive processes that are involved in their expression. Since the seminal work of Beach (1957), and Garcia and his colleagues (Garcia, Kimeldorf, & Hunt, 1957), several hundred studies of conditioned avoidance and conditioned preference have been conducted in rats (see Carr, Fibiger, & Phillips, 1989;Schechter & Calcagnetti, 1993, for reviews). Although conditioned place preference is the most extensively employed procedure, it can be considered a special case of a more general conditioning paradigm in which neutral stimuli are associated with biologically relevant events that have affective significance and subsequently elicit approach or avoidance (McDonald & White, 1993).…”

“…To our knowledge, no radiation receptors have been identified in any animal, but many studies have demonstrated behavioral responses to ra- diation, particularly by mammals and invertebrates. Radiation-induced spatial avoidance has been demonstrated experimentally in a variety of animals (Garcia et al 1957, Darenskaja et al 1966, and radiation has also been used as a conditioned stimulus in aversion tests (Peacock andWatson 1964, Cullen 1969) or for arousal (Smith et al 1963). These studies suggest direct detection of radiation.…”

In a gradient of gamma radiation ranging from 38.7 mC°kg—1°d—1 to background levels of 0.05 μC°kg—1°d—1, Tree Swallows (Iridoprocne bicolor) and House Wrens (Troglodytes aedon) avoided nesting in areas of high radiation. Nest boxes selected by swallows and wrens had a mean exposure rate of only 9.3 and 6.6 μC°kg—1°d—1, respectively. Lateral and canopy vegetation indices and nest hole height and direction could not explain the observed pattern of box selection. Of the boxes with low exposure rates, swallows selected those with little vegetation cover, whereas wrens chose boxes with heavy cover. It appears that the birds responded to radiation levels as low as 100 times background, but it is not clear whether they actually detected radiation or simply responded to secondary clues. The number of swallows and wrens fledged per box was unrelated to radiation exposure. The same was true for number eggs, hatching success, fledging success, incubation time, and nestling time. Breeding success was reduced because of infertile eggs, eggs with dead embryos, cracked eggs, predation, adverse weather, abandonment, and parasites. The logistic model was ideally suited for describing gains in mass in nestling swallows and wrens. Growth of nestlings was not related to radiation exposure as indicated by the growth rate constant, asymptotic mass, and the proportion of variation explained by the logistic model. Breeding and growth performance were similar in studies not involving experimental radiation. The data show that birds avoided adverse effects of radiation by judicious box selection. However, there were indications that at higher breeding densities birds may use high—exposure boxes, where breeding success or growth of nestlings may become reduced due to radiation.
