The behavioral repertoire of the sea anemone, Anthopleura
xanthogrammica, was investigated to test for the occurrence of any
immediate response to various regions of the electromagnetic spectrum.
Monochromatic radiations in the visible and ultraviolet spectral
regions were produced by a 150-watt xenon lamp or a ZOO watt mercury
vapor lamp...
Chemical dosimetry developed in response to needs created by
developments in the field of high-energy radiation. Shortly after the
discovery of X-rays in 1895 and of radioactivity in 1896, the deleterious
effects of ionizing radiation were recognized. To guard against the
injurious effects of radiation in medical application, dose-measuring
methods...
