Based on my 30 years of experience with toxic chemicals and radiological hazards, I do not consider the radiological exposures at CASTLE to be any worse than the normal occupational hazards of duty with the Department of Defense. I deplore the exaggerated and subtle distortion of the hazards of radioactive contamination and I caution the writers of this report to eliminate such controversial terms as: grave danger, in spite of these precautions, failure of the command, significant. Many of the reports rendered were uncoordinated and unevaluated to the point that misleading assumptions can be made. In the test business we had a saying that "a person did not understand radiological fallout until he had walked in it” and this philosophy still applies some 25 years later. We respect the hazard but we do not fear it. a SHS— ohn Servis Colonel, U.S. Army (Ret)
