Pre-Hospital Response to Events Involving Radioactive Materials Robert C. Beauchamp, RN BSN CEN NREMT-P REAC/TS Oak Ridge Institute for Science and Education
OBJECTIVE • Assist pre-hospital responders in the initial management of a radiation accident/incident. • Identify potential hazards when responding to a radiation accident
On Scene Basic Priorities • Safety of responders • Safety of victims • Course of action development • Contamination control • Consequence management Don’t be a Victim
What Hazards Safety of Responders
Safety of Victims • Physical hazards at the scene are most likely to force immediate evacuation • At some scenes the chemical nature of the contaminant may be more of a threat to the patient than its radioactivity • Immediate life-threatening problems will be medical and/or trauma in nature and must be cared for.
Victim Risk Analysis • Physical hazards assessment of the Scene. • Life threatening dangers to the victim. • Radiation level (accumulated dose to rescuers/victim) • Irradiation vs Contamination • Types of Contamination (a, b, g) • Area contamination status fixed, airborne, liquids
Mitigating the Radiation Exposure Hazard • Limit time devoted to on scene treatments, remember the Golden Hour. • Have a plan and stay focused. • Perform only the skills needed to sustain life while on the scene. • ABC, C-Spine, Massive external bleeding, major fracture stabilization
Course of Action Development • Scope of the Response • Team Organization (availability) OIC prior to IC identification Haz/Mat, Medics. Firefighters, Police, ? Field Deployment Medical Team(s) • PPE considerations – public safety, police, fire, EMS, and hospital staff
Course of Action Development (cont.) • Equipment: Survey meters, dosimeters, medical gear, litter device, extrication equipment, sheets. • Ingress & Egress routes with control measures • On-scene actions: TREAT LIFE THREATS Evacuation, search, medical care, victim identification
EPA Emergency Dose Guidelines No individual shall be required to perform rescue actions that might involve substantial personal risk.

Contamination Control • Most contamination will be on clothes. Atleastouterclothing should be removed before transport of patient to hospital (to minimize spread of contamination to ambulance and ED). • As much as possible, leave contaminated materials (including the clothes that were removed) at the incident scene. If receiving facility can identify source double bag and take it with you. • Send victim’s identification (in plastic baggie) to the ED with the victim.
Contamination Control • Use sheet or pillowcase to keep from kneeling on contaminated ground • Place equipment in plastic bags. Take in only the equipment you need. • Cover exposed surfaces in ambulance with plastic/sheet. Don’t create a hazard for yourself. • Delineate the contaminated area (signage, tape, markings)
Contamination Control • Restrict access to essential personnel & resources • Designate entry & exit points • Provide radiation monitoring at all entry and exit portals if possible • Establish decontamination sites as dictated by patient medical status • Limit removal of items from contaminated areas

Let’s Rescue a Patient From a Radioactively Contaminated Area
Know Your Protocols Radioactive Contamination Protocol
Donning PPE • Put on outer garment or scrubs (local protocol) • Put on shoe covers (local protocol) • Put on inner gloves (blue) • Tape sleeves and pants legs (masking tape/duct tape) • Outer gloves (two pair) • Head cover • Face shield • Mask (airway protection per local protocol)
Taping Initially Triple Glove
Approaching the Scene Initial Decision Tree • Are there chemical, physical or radiological threats to the responders? • Are there patients to be treated? • If radiation is the threat, then treat life threatening problems and remove patients from area.
Check patient/pre-rolled three sheets Normal Log Roll
Contaminated Clothing Now Contained Roll Sheet Away From Airway

Removing PPE • Outer booties (if worn) • Outer gloves • Pass dosimeter across control line (if used) • Remove tape at cuffs and sleeves • Head cover and face protection • Outer garments (over shoe covers) • Remove one shoe cover at a time/survey bottom of shoe/step across control line • Remove inner gloves/drop back into contaminated trash • Total body survey
Consequence Management of a Radiation Event • Continued medical support to victims & responders • Environmental clean-up & decontamination • Bioassays screening and, if indicated, whole-body counting • Decorporation therapy (if indicated) • Psychological counseling & support • Follow-up assistance
Suggestions • Assure warmth for disrobed victims. • Showering of victims is NOT normally indicated. • Control run-off of decon solution to avoid tracking to clean areas.
What Have We Learned? • Radiation incidents are manageable • Immediate actions are related to medical needs and are not related to radiation exposure or contamination issues. • Ionizing radiation is detectable and measurable. YOU CAN SEE IT WITH A METER • Responders can safely care for contaminated victims.
What’s the BIG picture You can handle this!
