A report on the Radiological Monitoring Course offered as part of the Milwaukee Civilian Defense Program. In the first course 250 firemen, policemen, and people with technical background were trained in the principles of nuclear physics, and the effects, detection, and measurements of radiation. The course consisted of a series of lectures, together with appropriate films on the fundamentals of atomic and nuclear physics. The laboratory sessions consisted in familiarizing the trainees in the handling, reading, and care of three different radiation measuring instruments. Small radium sources were used. The field sessions consisted of the survey of a three curie cobalt-60 source at a local football stadium.
