Population MonitoringPopulation Monitoring
The process of identifying, screening, and monitoring people for exposure to radiation or contamination with radioactive materials.
The process of identifying, screening, and monitoring people for exposure to radiation or contamination with radioactive materials.
Population MonitoringPopulation Monitoring
Evaluate potentially-affected population for:
– Needed medical treatment (both rad and non-rad related)
– Presence of contamination on body or clothing.– Intake of radioactive materials– Removal of external or internal contamination
(decontamination)– Radiation dose received and the resulting health
risk from the exposure– Long-term health effects (registry)

Current Planning GuidanceCurrent Planning Guidance
The Federal Emergency Management Agency has exercise evaluation criteria requiring that state emergency response plans demonstrate the ability to monitor 20% of the potentially exposed population within 12 hours upon arrival at a relocation center.
Reference: “Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in support of Nuclear Power Plants” NUREG-0645 FEMA-REP-1 Rev 11)

How is this demonstrated?How is this demonstrated?For nuclear power facilities, affected populations could range from a few hundred to several hundred thousand individuals. Most state and local health departments attempt to demonstrate this with:
– Hand-held radiation survey instruments– Portal monitors (for only beta/gamma
monitoring) are used by only a handful of state agencies (the DOE has 13 deployable with the FRMAC assets)
– Alpha portal monitors have limited capabilities and are not easily transportable

Laboratory AnalysesLaboratory Analyses• Conventional methodology
– 24-hr urine sample– 3-7 days turnaround time– 5-40 samples/day/lab
• Improved methodology (for population screening)– 1-50 ml “spot” sample– 4-36 hours turnaround time (multiple radionuclides)– 100-500+ samples/day/lab
• Field screening and prioritization important• Increase number of public health laboratories
capable of doing such analyses

CDC GuidanceCDC Guidance
PurposePurpose
• State/local emergency response and public health authorities can use this Guide to:– Evaluate their emergency response plans– Identify/prioritize staffing needs, training
requirements, and necessary material assets.
– Further develop mutual assistance programs– Be better prepared to prioritize allocation of
existing resources in actual response

Guiding PrinciplesGuiding Principles
• The first priority is to save lives: respond to and treat the injured first.
• Contamination with radioactive materials is not immediately life-threatening.
• Initial population monitoring activities should focus on preventing acute radiation health effects. – Cross contamination issues are a secondary
concern

• Scalability and flexibility are an important part of the planning process.
• The State radiation control program is a key resource for implementing the plans outlined in this guide.– Establish relationships with other
radiation experts/resources in the community (hospitals, universities, etc.)
