Abstract

The use of asbestos, a substance widely recognized as toxic, is banned in many countries, and the demolition of asbestos-containing buildings has increased in recent years in Japan. Conventional methods of removing asbestos-containing materials pose a risk of lung cancer and other diseases because they scatter asbestos in the air. Here, we demonstrate that a laser beam can be used to detoxify asbestos and suppress its scattering. The scattering of amorphous materials with the same composition as asbestos was observed in dust of asbestos-containing materials.
