From the Introduction: "In the event of a large-scale radiological or nuclear event it is likely that many NYC and other agencies will participate in response efforts. While overall radiation safety and health decisions will be made by the Command Element, the Citywide Incident Management System (CIMS) requires each agency to be responsible for ensuring the health and safety of its own workers. The Command Element and responding agencies will be supported by subject matter experts from advisory groups including the Radiological Advisory Committee (RAC) and/or the multiagency Health and Safety Workgroup convened to develop the incident health and safety plan (HASP) according to CIMS Annex D. This Field Guide is intended to provide guidance to Health and Safety Officers (HSOs) concerning radiological hazards and the recommendations to control potential exposures. Radiation and radioactivity pose unique challenges and risks that are subject to local, State, and Federal regulations, including dose limits, requirements for posting radiological areas, and specifications on the use of radiation dosimetry. There is a minimum level of qualifications and/or experience that the HSO at the scene of a radiological emergency must possess to ensure staff is adequately protected and that regulatory compliance is achieved."
