CONFIRMATION OF SPRAYING CONDITION OF ASBESTOS TREATMENT AGENT BY USING WIDE-BAND ULTRASONIC WAVE

Abstract

The health hazard caused by asbestos has become a serious social issue, and thoroughness in prevention measures of scattering asbestos becomes an important problem. Complete removal or careful asbestos containment procedures will be necessary, if sprayed asbestos are found. Asbestos containment is performed in order to reduce or eliminate the risks of asbestos exposure on human health. In asbestos containment, it is very important to confirm the spraying condition. In this study, it proposes the method of confirming the spraying condition by using the wide-band ultrasonic wave.
