The radiation response, quantified by the dose-log survival curve, of spores Bacillus pumilus subjected to irradiation in a 150 kV x-ray beam was examined and compared with response obtained reference cobalt-60 beam. were irradiated at doses ranging from 2 kGy 11 kGy. same for both qualities within measurement uncertainties. Combining these findings our previously published data, resistance B. ...

A cobalt spot test was recently developed (1). Testing for cobalt release is performed by dipping a white cotton stick into a clear yellow cobalt test solution containing nitroso R salt, followed by rubbing of the cotton stick for 20–30 seconds against the test item. A colour change from yellow to red–orange indicates a positive test reaction. The spot test detects approximately 8 ppm cobalt in...

The Report on Carcinogens includes two separate listings (i.e., profiles) for cobalt-related exposures: Cobalt and Cobalt Compounds That Release Cobalt Ions In Vivo and Cobalt-Tungsten Carbide: Powders and Hard Metals. Cobalt and cobalt compounds as a class are listed for the first time in the Fourteenth Report on Carcinogens, and this listing includes and supersedes the listing for cobalt sulf...

The effects of methylcobalamin (vitamin B12) injection (75mg kg ) on cobalt levels in autism spectrum disorders (ASDs) and potential toxic effects of cobalt on human neurons were evaluated. A cohort of ASDs (n1⁄4 72) presenting to the Genetic Centers of America were evaluated for the frequency of methylcobalamin injections and cobalt levels using Laboratory Corporation of America (LabCorp) test...
