Abstract

DURING work on the irradiation of bakers' yeast, Saccharomyces cerevisiae, it was found that irradiation of the buffers, sodium cacodylate (sodium dimethylarsinate), (CH3)2 As O O Na, and of tris (hydroxymethyl) aminomethane (=tris= 2-amino-2-hydroxymethyl-1, 3-propanediol), yielded substances giving positive Fiske–SubbaRow1 and ninhydrin2 colorimetric tests, respectively. Further investigations have been carried out to assess the value of these systems in radiation dosimetry.
