This progrmed course of study is designed to prepare local government officials and individual citizens to act in nuclear emergencies or disasters. Each of the four units has two lessons beginning with a brief overview and proceeding with self study frames. Line drawings are used to illustrate effects. Topics covered are the radiological monitor in civil defense, fallout effects, exposure guidance, RADEF instruments, protective measures, decontamination procedures, dose and dose rate calculations, and radiological monitor tasks, procedures, responsibilities, and reporting. An additional information appendix follows the same format but is not provided with tests; it covers nomograns and peacetime nuclear hazards.
