The Effect of Cobalt-60 Gamma Radiation on Passive Immunity *
A considerable amount of work has been reported in the literature on the effect of x-rays on antibody formation and immunity. With the exception of the reports from our laboratory,5"' the depressing effect of cobalt-60 gamma radiation upon immunity and antibody formation has not been reported. It would seem logical that x-rays and gamma rays should have a similar physiological effect. However, ...
متن کاملComparison between Amperometric and Chemiluminescence methods in detection and dosimetry of cobalt-60 gamma ray emission
Background: Hydrogen peroxide (H2O2), produced by gamma ray irradiation to watery solution, was used as an analytical parameter for dosimetry of cobalt-60 (60Co) radiation. Materials and Methods: Detection of the produced H2O2 was carried out using two methods: an amperometric biosensor fabricated by immobilization of anthraquinone 2-carboxylic acid modified horseradish peroxidase on glassy car...

متن کاملThe Graphite Calorimeter as a Standard of Absorbed Dose for Cobalt-60 Gamma Radiation
Absorbed dose to water in a cobalt-60 gamma-ray beam has been determined using a thick-walled graphite ionization chamber. The chamber was calibrated in a graphite phantom against a graphite calorimeter, and the graphite calibration factor was converted to a water calibration factor using published energy absorption coefficient ratios and a measured replacement factor. Comparisons between the g...
متن کاملMeasurement of Cesium-137 and Cobalt-60 Gamma Radiation With a Pressure Ionization Chamber
The characteristics of the pressure ionization chamber at t he National Bureau of Standards have been studied for the gamma radiation from a cesium-137 sou rce (0.6614 Mev) and from a cobalt-60 source (1.1715 and 1.3316 Mev). The dosage rates produced in air by these sources were measured with this chamber with an accuracy of about 2 percent. Dosage rates obtained with an extrapolation chamber ...
