Management Modifiers for
Treating Radiation Contamination
Burns and the Radiation Contamination Algorithm
- Both thermal and radiation burns may occur in radiation emergencies.
- Thermal burn injury + radiation exposure = combined injury
- Prognosis worse than the same burn injury or exposure alone
- Burn injury + contamination
- Prognosis will depend on the specifics of each case.
- Burn wounds must be decontaminated before definitive burn care is delivered.
- When prioritizing delivery of scarce resources in radiation mass casualty emergencies, it is appropriate to consider prognosis related to
- Implementation of "Crisis Standards of Care" may be needed in disaster situations.
- This algorithm and supporting material provide guidelines, not mandates.
- See Burns page for details about thermal burns.
- See Cutaneous Radiation Syndrome page for details.

Trauma and the Radiation Contamination Algorithm
- Trauma + radiation exposure =
combined injury
- Prognosis is worse than the same traumatic injury or exposure alone.
- Trauma + radiation contamination
- External contamination
- By itself, will not usually worsen trauma-related prognosis
- Performing emergency life- and limb-saving tasks/surgery before completing formal external decontamination is appropriate.
- Removing all clothes can eliminate about up to 90% of external contamination when there is not time to conduct formal
decontamination.
- See Timing of Surgery for details.
- Internal contamination
- Some trauma victims may need life- and limb-saving surgery before the level of
internal contamination is known.
- Bioassays to quantify the level of internal contamination are time consuming and may not be widely available at least initially in very large mass casualty incidents.
- See Radioactive Shrapnel for management guidance.
- When prioritizing delivery of scarce resources in radiation mass casualty emergencies, it is appropriate to consider prognosis related to
- Extent of trauma
- Extent of external whole body radiation exposure and significant
exposure from any
internal contamination, e.g.,
Polonium-210
- Percent body surface area and depth (i.e., degree) of burns
- Pre-existing medical conditions
- Implementation of "Crisis Standards of Care" may be needed in disaster situations.
- This algorithm and supporting material provide guidelines, not mandates.
- See Radiation + Trauma page for details.
- See Mass Casualty page for details.

Mass Casualty Emergencies and Radiation Contamination Algorithm
- The REMM Contamination Algorithm
- Is appropriate for events small enough to permit individualized victim evaluation and treatment, including decontamination
- Algorithm modifications may be needed for radiation mass casualty emergencies because of
- Contamination algorithm modifications during radiation mass casualty emergencies
- External contamination
- Limiting/altering radiation surveys
- Conducting one-time screenings of head, neck, hands, and forearms
- Avoiding multiple whole body screenings and re-evaluations during initial triage
- Altering targets for decontamination
- Directing ambulatory victims away from medical facilities to community reception centers and
- Providing instructions for self-decontamination at home
- Internal contamination
- Bioassays to quantify the level of internal contamination are time consuming and may not be widely available at least initially in very large mass casualty incidents.
- Empiric treatment of internal contamination may be advisable in highly selected, life-threatening circumstances, even in the absence of definitive diagnostic test results.
- When prioritizing delivery of scarce resources in radiation mass casualty emergencies, it is appropriate to consider prognosis related to
- Extent of trauma
- Extent of external whole body radiation exposure and significant
exposure from any
internal contamination, e.g.,
Polonium-210
- Percent body surface area and depth (i.e., degree) of burns
- Pre-existing medical conditions
- Implementation of "Crisis Standards of Care" may be needed in disaster situations.
- This algorithm and supporting material are guidelines, not mandates.
- See Mass Casualty page for more details.
- See Radiation + Trauma for more details.

Timing of Surgery and the Radiation Contamination Algorithm
- External contamination + trauma requiring emergency surgery
- Formal external decontamination is appropriate.
- When clinical urgency does not permit formal decontamination
- Removal of contaminated clothing can eliminate about up to 90% of external contamination.
- Traditional surgical skin prep will also help eliminate skin contamination.
- Avoid pre-op shaving, if possible, to help maintain an intact skin barrier against radioactive materials.
- Activate hospital emergency radiation response plans
- If contaminated patients are admitted to the hospital in a mass casualty situation.
- To ensure the health and safety of hospital staff and healthcare team
- To manage/minimize potential contamination of hospital spaces, including operating and radiology suites
- This algorithm and supporting material provide guidelines, not mandates.

Blood Products Use and the Radiation Contamination Algorithm
- Patients with certain kinds of internal contamination (e.g.,
Polonium-210) can be at risk for
Acute Radiation Syndrome (ARS)
- Patients with ARS will be immunosuppressed.
- They are at risk for post-transfusion graft versus host disease (GVHD).
- Guidelines suggest that these patients should receive blood products that have been both
- Irradiated and
- Leuko-reduced
- If irradiated, leuko-reduced blood is unavailable,
- Emergency transfusions may still be considered.
- Attention should be paid to possible post-transfusion GVHD.
- Most patients with external contamination but no known
radiation exposure
- Are unlikely to develop ARS
- Should be evaluated for ARS before receiving blood products
- This algorithm and supporting material provide guidelines, not mandates.
- See Blood Products page for more details.

At-Risk / Special Needs Populations and the Radiation Contamination Algorithm
- See the At-Risk / Special Needs Populations page
- Describes groups especially vulnerable to the effects of radiation
- These populations may require
- Effective and ethical allocation of medical resources is crucial for all populations.
- This algorithm and supporting material provide guidelines, not mandates.
