TB 056- Radiological Emergency Operations

Question 1

________ is any form of energy that travels through space or matter

Answer 1

Radiation

Question 2

What does N.O.R.M. Stand for?

Answer 2

Naturally Occurring Radioactive Material

Question 3

What is N.O.R.M.?

Answer 3

Naturally Occurring Radioactive Material- some existing radiation

Question 4

What is Non- Ionizing radiation?

Answer 4

Radiation that does not have enough energy to remove electrons from atoms and molecules. Heats substances like a microwave heats food

Ex- ultraviolet radiation from the sun and tanning beds

Question 5

What is ionizing radiation?

Answer 5

Radiation in a form of energy that acts by removing electrons from atoms and molecules that include air, water and living tissue
Biggest threat***

Question 6

What are the different types in Ionizing radiation?

Answer 6

ALPHA- low power (stopped by paper)
BETA- highly energetic (stopped by clothing) can penetrate skin and cause burns. Most hazardous if inhaled/ ingested
GAMMA- high energy, short wavelength electromagnetic energy emitted from the nucleus of atom. (Stopped if shielded by lead/ concrete)
NEUTRON- small atomic particles possessing no electrical charge and are typically found within atoms’ nucleus (stopped y shielding with thick concrete/ lead)

Question 7

___________ __________ __________ or RMR is any significant, unauthorized release of a radioactive material into the environment from a fixed facility or transportation vehicle

Answer 7

Radiological Material Release

Question 8

__________ _________ __________ or R.E.D. Is a containerized radioactive material that directly exposes the public to radiation but does not release contamination

Answer 8

Radiation Exposure Device

Question 9

______ _______ ______ or R.D.D. Is a device can cause the deliberate release of radioactive material by explosives, by contamination of water or ventilation system, or by a release into the environment

Answer 9

Radiological Dispersal Device

Question 10

What is a Nuclear Device?

Answer 10

An illicit weapon that is acquired or fabricated by a terrorist group that can produce a nuclear explosion

Question 11

_______ (R) is the measurement of the amount of energy in the air that may reach the body

Answer 11

Roentgen “rankin”
Measured by total accumulated dose of radiation absorbed by the body over time

Question 12

What is the ALARA principle?

Answer 12

“As Low As Reasonably Achievable”
Minimize time spent in areas where radiation exposure may occur and maximizing distance between a worker and a source of radiation exposure

Question 13

_______ orders evacuation or shelter- in- place order to deal with tactical priorities of “loss limiting” and “victim/ occupant stabilization”

Answer 13

Incident Commander

Question 14

_________ is an invisible cloud- like formation which is projected by such factors as: meteorological conditions, size of release, wind speed/ direction, and type of radioactive isotope

Answer 14

“Plume”

Question 15

90%

Question 18

Initial Devon wash time should be between ___ secs and ____ mins to ensure thorough soaking, depending on the situation and agent involved

Answer 18

30 secs and 3 mins

Question 19

Due to radioactive materials hazard potential, it is mandated that these cargos are placarded with 1 of 3 types of placards. Name the 3

Answer 19

Transportation- 10’’x10’’ with word “radioactive”, recoil pictographs, a DOT number of “7”

Packages- 4’’x4’’, label with name on contents, activity (number of disintegration/ min) transport index (amount of radiation at 3 ft)

Fixed facilities (hsp’s, dental/ medical facilities, universities, and industrial sites)- sign/ label will be posted on entry doors, storage vaults, cabinets or containers
