Title: Innovations of Masatoshi Ota in Airborne Radon and Thoron Measurement

Introduction

Masatoshi Ota is a notable inventor based in Niigata, Japan. He has made significant contributions to the field of environmental measurement, particularly in the detection of airborne radon and thoron. His innovative approach has led to the development of a novel method that enhances the sensitivity and accuracy of these measurements.

Latest Patents

Masatoshi Ota holds a patent for a method for measuring radon and thoron in the air. This method allows for the separate measurement of radon and thoron with high sensitivity, utilizing a compact device structure that is unaffected by environmental influences. The technique involves measuring Cherenkov light generated when airborne radon and thoron are adsorbed onto an absorbent. The subsequent beta rays emitted during the disintegration process of radon and thoron pass through the absorbent, enabling precise measurement. The method also determines the mixture ratio between radon and thoron based on the decay time of the Cherenkov light. Porous glass, with fine pores ranging from 0.3 to 30 nm in diameter, is preferably used as the absorbent.
