Module E (Quizlet 4)

Technical Escort - Radiological Operations

QuestionAnswer
Ionizing radiation definition Radiation in the form of a particle or pure energy that possesses enough energy to remove an electron from an atom, which includes alpha, beta, neutron and gamma/x-ray
Alpha particle definition Radiation consists of two protons and two neutrons and is identical to the Helium 4 atom minus the 2 electrons
Beta particle definition Radiation is equivalent to a high-energy electron that has been ejected from a nucleus of an atom
Neutron particle definition High speed, very penetrating particles emitted during fission or fusion reactions, causes other elements or material to become radioactive
Gamma/X-ray particle definition A form of electromagnetic radiation, a photon of pure energy
What is the Gamma and X-ray difference Gamma originates within the nucleus and x-ray forms outside the nucleus
Geiger Muller tube definition Ionizing radiation dislodges electron from gas inside tube and electron hits anode to produce a measurable current
Scintillation definition Ionizing radiation strikes a crystal that releases a photon that can be measured
Ion chamber definition Ionizing radiation dislodges electron from gas and electron hits anode to produce a measurable current; chamber is enclosed and affected by pressure
What SI unit is equivalent to Curie(CI)? Becquerrel
What SI unit is equivalent to rad? Gray (Gy)
What SI unit equivalent to rem? Sievert (Sv)
What SI unit equivalent to Roentgen (R)? One does not exist
What technology does AN/UDR-13/14 use? Geiger Muller tube
What is the measuring capabilities of the AN/UDR-13? Measures/displays gamma radiation dose rate 0.001-999 cGy/hr, measures, stores and displays total does from 0-999 cGy and battery life normal is 100 hrs and Sleep mode is 2,000 hrs
What is the measuring capabilities of the AN/UDR-14? Measures/displays gamma radiation dose rate 0.001mGy-999 cGy/hr, measures, stores and displays total does from 0.001mGy--999 cGy and battery life normal is 100 hrs and Sleep mode is 1,000 hrs
What are the capabilities of the AN/UDR-13/14? Auto ranging, designed for use after nuclear event, programmable alarms both audible and/or visual, battery saving function and pre-settable alarm capability for Dose/Dose rate
What are the limitations of the AN/UDR-13/14 Accuracy -+ 20% of true dose and does rate, operates up to 95% humidity, operating temp is -51 to 120 deg F and storage temp is -60 to 160 deg F
What technology does AN/VDR-2 use? Geiger Muller tube
What are the capabilities of AN/VDR-2? Low and high range GM tube, auto ranging, designed for use after nuclear event, programmable alarms both audbile and visual, defaults to rate mode
