An area was considered a full radex area if the con- tamination exceeded 100 mr/hr and full protective clothing was required fc entry into it. Limited radex areas were established as necessary where t contamination was in excess of 10 mr/hr but less than 100 mr/hr. In the areas the clothing requirements were dictated by the situation and the job be performed. In those cases in which alpha contamination presented a pr lem, no hard and fast rule concerning full radex areas was established.
