Q

Radiological hotline est at 2 mR/hr (taken from environment, not people), however people taken out may have higher levels than 2 mR/hr before being decon. Choose incorrect
A. Hotline is edge of hot zone after which no contamination present
B. Greater than 2 mR/hr is hot zone and less than 2 mR/hr is warm zone
C. Hot zone restricted to rescue and fire suppression
D. FFs shall direct ambulatory victims to proceed to Warm Zone for decon, if needed

A

B less than 2 mR/hr is cold zone. Warm zone is a specific area near the edge of the hotline, usually superimposed in the cold zone. Warm zone does not encircle the source of radiation. Rather, it is a small defined location used for decontamination or SRA where the radiation levels are as low as possible

Q

Radiological Emergency correct
A. 1st units obtain readings of 30 mR/hr so IC orders to delay victim rescue and fire suppression until units w/Ludlum meters arrive
B. Accidental breach in the container, Fire Marshals were special called
C. Members were instructed not to enter the Hot Zone except for rescue, recon, or fire suppression
D. Material aerosolized so air intakes of nearby bldg were opened to maintain positive pr in bldg
E. Non-ambulatory pts in nearby hospital would receive a dose of 7 REM, so it was decided to evacuate through a radioactive plume

A

C
A Initial ops for victim rescue and fire suppression should not be impeded for rates in the mR/hr range
B Radiological Emergency intentional- special call Marshals for security and crime scene preservation
D shut down air intakes for surrounding bldgs if the radioactive material is aerosolized
E 10 Rem for special groups such as nonambulatory
hospital patients, prison residents, nursing home residents

Q 
Transport Index (TI) incorrect
A. TI indicates max level of radiation in mR/hr at one meter from surface of package
B. If levels of radiation exceed TI, integrity of package may have been compromised/breached
C. TI applies to Alpha, Beta, and Gamma 
D. TI of a package should not exceed 10 mR/hr; total TI of a vehicle's shipment may not exceed 50 mR/hr
A

C TI applies to levels of gamma radiation only. Readings of alpha or beta particles indicate the package may have been breached and the shielding compromised

Q

Incorrect for monitoring background for radiation
A. Using Radalert 50, all units will monitor area IFO qtrs for 5 min at designated times
B. Background info recorded on RAD-3 report. Elevated background readings over .05 but under .9 mR/Hr shall require Off to fwd copy of RAD-2 “Elevated Background Radiation Readings Above .05 mR/Hr to the Battalion
C. Copy of data chart must be fwd to unit’s Battalion and forwarded to Division.
D. Radalert 50 battery changed on JAJO 1st of each yr

Q 
Potassium Iodide (KI) thyroid "blocking agent" correct
A. KI is important in event of radiological incident involving release of radioactive iodine. KI must be taken early in event
B. KI will protect thyroid gland from radioactive iodine and may protect other internal organs from radiation
C. Adult dose following exp is one tablet ASAP. Taking a higher dose will offer additional protection
D. Women who are pregnant or breastfeeding should not take KI as it is harmful to breast milk and baby
A

A
B KI does not prevent the effects of other radioactive elements. Using KI will only protect the thyroid gland from radioactive iodine.
C Taking a higher dose or taking KI more often than recommended will NOT offer more protection and can cause severe illness and death due to allergic reaction
D Women who are pregnant or breastfeeding should also take KI to protect themselves and their breast milk.

17
Q

Incorrect at a massive radiological emergency:
A: Dry decontamination measures were ordered to expedite the transfer of patients to EMS for treatment.
B: Since the dose inside of a nursing home was projected to be a maximum of 6 REMs, the DC did not evacuate the nursing home residents.
C: The Operations Chief designated a Rescue Company Officer to oversee Extraction Task Forces to achieve proper lifesaving emergency medical care in high-rise buildings and subway tunnels.
D: Extraction Task Forces included FFs and EMS personnel in proper PPE to rapidly triage, treat and move patients with life-threatening injuries as quickly as possible out of the area to ambulances outside.

A

C) The Operations Chief may need to designate a BC to oversee Extraction Task Forces to achieve this goal in high-rise buildings or subway tunnels.
B) Evacuate if the projected dose inside a building will reach 5 Rem for the general population or 10 Rem for special groups such as non-ambulatory hospital patients, prison residents, or nursing home residents.

Q

Transport Index correct:
1 - Package A has a transport index reading of 10
mR/hr at 1 meter from the package
2 - Meters are detecting Alpha, Beta, & Gamma Radiation.
3 - Entire truck’s shipment has a transport index reading of 100 mr/hr.
4 - Package B has a transport index of 5 R/hr at 1 meter from the package
A: 1 only Indicates a breached package
B: 1 and 3 only indicate breached packages
C: 2, 3, and 4 only indicate breached packages
D: 2 only indicates breached packages

A

ERP Addendum 4 - Radiation pg 33

  1. 5.3 - If levels of radiation exceed the Transport Index, the integrity of the package may have been compromised or breached.
  2. 5.4 - The TI applies to levels of Gamma Radiation only. Readings of Alpha or Beta particles indicate the package may have been breached or the shielding compromised. (#2)
  3. 5.5 - The Transport Index of a package should not exceed 10 mr/hr (#1 is 10 indicating no breach, #4 is 5 R indicating breach)
  4. 5.6 - The Transport index of a shipment should not exceed 50 mr/hr

Q 
You are the first arriving chief officer in charge of a large  radiological incident. You conduct your initial size-up  and give a preliminary report to the dispatcher. You transmit the 10-80-1 and start establishing a Safe Refuge Area (SRA) for decontamination. The SRA should be established how far away from the suspected explosion origin site?
A: 100 yards
B: 500 meters
C: 300 feet
