Protection from contamination by ²¹¹At, an enigmatic but promising alpha-particle-emitting radionuclide.

ABSTRACT:

Purpose

²¹¹At, a promising alpha-particle-emitting radionuclide, can easily volatilize and contaminate the environment. To safely manage this unique alpha-particle-emitting radionuclide, we investigated the permeability of four types of plastic films and two types of rubber gloves against ²¹¹At and identified suitable materials that prevent contamination by ²¹¹At.

Methods

Four types of plastic films, polyethylene, polyvinylidene chloride, polyvinyl chloride, and a laminated film, and two types of rubber gloves, latex and nitrile, were examined. Small pieces of filter paper were covered with these materials, and a drop containing 100 kBq of ²¹¹At was placed on them. The radioactivity of the pieces of filter paper under the materials
