Community Hardening: Radiation Melinda Johnson Denver MMRS Program Coordinator melinda.johnson@rmpdc.org Welcome! Session Goal: To understand how one community calculated the risks of radiation exposure and the steps taken to mitigate
Welcome!
Session Goal:
To understand how one community calculated the
risks of radiation exposure and the steps taken to mitigate that risk.
To leave with the knowledge necessary to begin
such a program within your community.
Session Objectives
Identify ways to determine community risk of
radiation exposure.
Understand what needed services are most at
risk to radiation contamination.
Identify ways to protect, prevent, respond and
eventually recover from a radiation exposure incident.
Why is this needed?
National Planning Scenarios 1 & 11
Unknown/uncertain contamination Self-referring victims Surreptitious exposure
Radiations of concern
Penetrating/non-penetrating External vs. internal
Contamination control Recognition that First Receivers were a gap in
planning
Types of Exposures
Radiological Accidents:
Healthcare facilities, specialized imaging centers,
medical waste facilities.
Industrial or transportation incidents.
Terrorism Scenarios:
Dirty Bomb Radioactive Device
Radiological Materials
Millions of radioactive sealed sources are used around the world for
legitimate and beneficial commercial applications such as cancer treatment, food and blood sterilization, oil exploration, remote electricity generation, radiography, and scientific research. These applications use isotopes such as Americium-241, Californium-252, Cesium-137, Cobalt-60, Curium-244, Iridium-192, Plutonium-238, Plutonium-239, Radium-226, and Strontium-90. Many of these radiological sources are no longer needed and have been abandoned or orphaned; others are lightly guarded, making the threat of theft or sabotage significant. Currently, there are thousands
- f civilian locations worldwide with dangerous high activity radioactive
sources.
1,000 curies of radioactivity (about the size of a roll of coins) is all that is
needed to make a large radiological dirty bomb.
Step One – Identification of Need
While conducting all hazards planning each region
conducts a vulnerability assessment.
This assessment raised our awareness of the numbers
- f facilities that we knew had radioactive sources –
and those whom we only suspected had them.
We realized that should there be a problem with one
- f those sources, we wouldn’t know, and wouldn’t
have been able to respond.
Step Two – What are the Risks?
In examining the sources in our community we also
had to think about the realistic risks:
Leaks Abandoned Sources Stolen Sources And less likely – a Terrorist Attack (aka Dirty Bomb)
Who would be impacted?
Infrastructure – Hospitals, government buildings, etc. EMS Law Enforcement
Dirty Bomb
- The term dirty bomb is primarily used to refer to a radiological dispersal device
(RDD), a speculative radiological weapon which combines radioactive material with conventional explosives. Though an RDD would be designed to disperse radioactive material over a large area, a bomb that uses conventional explosives would likely have more immediate lethal effect than the radioactive material. At levels created from most probable sources, not enough radiation would be present to cause severe illness or death.
- Since a dirty bomb is unlikely to cause many deaths, many do not consider this to
be a weapon of mass destruction. Its purpose would presumably be to create psychological, not physical, harm through ignorance, mass panic, and terror. For this reason dirty bombs are sometimes called "weapons of mass disruption". Additionally, containment and decontamination of thousands of victims, as well as decontamination of the affected area might require considerable time and expense, rendering areas partly unusable and causing economic damage.
- No dirty bomb has been used, though unexploded devices have been developed.
Step Three: Deciding what to Do
Once we looked at the risks and decided that
yes, we needed to take some action we had to decide WHAT to do.
Strategies include purchasing of
pharmaceuticals and equipment, outfitting and training decontamination teams - both hospital and fire based, as well as work with EMS to protect them post-exposure.
Step Four: Setting the Table
Who needs to be there?
Emergency Managers Toxicologists Hospitals Private Sector Partners EMS DHS/HHS Grantees (they have the $$) Law Enforcement (CAIC) Fire Departments – decontamination response
Step Five: What Can We DO?
Protect
Encourage private sector partners to protect their
sources and if possible participate in government programs that assist them with this.
In determining how to best protect a facility from
contamination from radiation we elected to use a wall mounted portal radiation device.
Purchase dosimeters for fire and law enforcement.
Equipment
Due to the cost of the
equipment we approached our State Homeland Security Grant program and asked for funds to purchase Ludlum area monitors and survey meters.
Stockpiling
There are many differing opinions on
stockpiling pharmaceuticals for response to a radiological event.
Where stockpiling is occurring it is without
standardized guidance.
Everyone is essentially “doing their own thing”
with regard to stockpiling.
Stockpiling
For example, there are 124 MMRS cities in the United States, they have
been tasked with stockpiling pharmaceuticals in the event of a disaster, however they have received no guidance on radiation stockpiles and each community is left to it’s own devices and decisions.
The Problem with Stockpiling
The Problem with Stockpiling
Antidotes and treatments are expensive Have limited shelf-lives Likely to be used in large quantities, but
rarely
The Problem with NOT Stockpiling
Staff Fear – will they want to respond if they
are in danger of exposure?
These antidotes are most effective when
administered immediately after exposure, or in the case of KI, before exposure. Do you have time to wait to receive the drugs?
The Strategic National Stockpile
A Federally Funded Repository of: Antibiotics Vaccines Immunoglobulins Chemical antidotes Radiation antidotes Antitoxins Life-support medications IV administration Airway maintenance supplies Medical/surgical items
SNS Push Packages
Strategically located
throughout U.S.
Supplement and
re-supply state and local public health agencies in the event of a national emergency
The SNS can be shipped
anywhere within the U.S. or its territories and should arrive to the scene within 12 hours
Stockpiling Questions
Where should you stockpile?
Local, i.e. Hospitals Community Region National, i.e. Strategic National Stockpile
How much do you stockpile? How do you
know you have enough?
Stockpiling Determinations
The decisions of if and how to stockpile medical
countermeasures should be made after comprehensive threat and vulnerability assessments are conducted at the national, state, regional and local levels.
These assessments are then combined with the modeling of
plausible scenarios. Once combined, these activities can provide an estimate of the number of persons who might be exposed if an even were to occur.
For any stockpiling program to work, activation, distribution
and local incident management systems must be in place and exercised.
Stockpiling Determinations
Another helpful tool in determining how
much Prussian blue to stockpile is a program developed by Johns Hopkins University called the Electronic Mass Casualty Assessment & Planning Scenarios - EMCAPS.
This tool is free and may be downloaded from: http://www.hopkins-cepar.org/EMCAPS/EMCAPS.html
What did WE do?
We worked with the toxicologists from the Rocky
Mountain Poison and Drug Center to determine what our exposure risks were, and what we should stockpile.
We have purchased the following:
Radiogardase (Prussian Blue) SKKI Duo Dotes Cyano kits Antibiotics
Concept of Operations
We have a risk of radiological exposure. We have a need to protect valuable assets, i.e.
hospitals & EMS from contamination.
If there is contamination we need a way to
determine what it is and how to treat it.
Decontamination
In our 10-County Region the two MMRS programs
have equipped 5 mass decontamination teams.
Fire Based Able to respond within 30 minutes Able to decontaminate large numbers of people Able to decontaminate equipment Has an associated HAZMAT team
We have also equipped hospitals with interoperable
decontamination equipment and training.
Communications
One reoccurring issue is how to communicate to
first-responders that they may have been exposed?
What you do regularly works best. Use the same mechanism currently in place for infectious
disease notification.
If law enforcement or fire are the first to discover
radioactivity they notify dispatch who notifies
- hospitals. If this step fails, the detectors will alarm
notifying hospitals.
Plans, Training & Exercise
We worked with individual hospitals to have
response plans in place when the detector actually goes off.
Part of this involved training from Susan
Eckhert of Health One in Washington DC.
Susan headed an HHS funded study on radiation
monitoring in hospital emergency departments.
Plans, Training & Exercise
Part of the planning process was to engage
hospitals, law enforcement and fire departments to understand who had what responsibility when the alarm sounded.
The second step is to exercise the plans:
Tabletops Drills Full scale
Plans, Training & Exercise
MMRS also worked with the State and the
Center for Domestic Preparedness (CDP) to train hospital response teams in appropriate decontamination protocols and processes.
What PPE to use? How much treatment to give prior to decon? How to assemble and staff a team?
Results
While still a work in progress, the North
Central Region of Colorado is prepared to respond to a radiological emergency by treating patients for specific types of radioactive exposure, protect hospitals (and working on other public buildings) from contamination and know how to communicate exposure risks back to first responders.
