METHOD OF TESTING MATERIALS FOR CANCER PRODUCTION

摘要

FIELD: analyzing or investigating materials. ^ SUBSTANCE: method comprises recording the curve of inhibition of probability of producing ortho-positronium by a standard dissolver (e.g., cyclohexane) by means of carbon tetrachloride, recording the curve of inhibition of probability of producing ortho-positronium by the material to be tested, and comparing the curves to find the presence or absence of carcinogenic properties of the material to be tested. ^ EFFECT: enhanced efficiency.
