Department of Dermatology, Karolinska Hospital, Stockholm, Sweden.

The exposure to grenz rays of office personnel handling a grenz ray unit working with 10 kV voltage was investigated for different treatment situations. Scattered and leakage radiation, and primary radiation at some distance from the grenz ray unit were measured. Air absorption was found to be most important. Direct exposure of the operator to the primary grenz ray beam at a distance of 4 m was practically nil. At a distance of 2 m from the unit, the operator is permitted to be exposed 100 h per year; at a distance of 1 m, the permitted exposure of the direct beam is 3 h per year. Scattered and leakage radiation from the unit was of no importance and certain clothing was demonstrated to promote absorption.
