RTE 2563 UPDATED KEY EXAM Questions
And CORRECT Answers
Discovery of X-rays - CORRECT ANSWERS 1895
Ionization can cause - CORRECT ANSWERS - creation of unstable atoms
- Production of free electrons
- Production of low energy photons
- Creation of reactive free radicals capable of poisoning cells
- Creation of new biological molecules detrimental to the living cellInjury to the cell that may manifest
itself as abnormal function or loss of function
ORP - CORRECT ANSWERS Optimization for Radiation Protection; a synonym of ALARA
What are the three basic principles of radiation protection? - CORRECT ANSWERS Time
Distance
Shielding
BERT - CORRECT ANSWERS Background equivalent radiation time- method compares the
amount of radiation received from radiography imaging and the natural environment
- Based off of 3 mSv per year
Based off of BERT a chest X-ray is equivalent to - CORRECT ANSWERS 10 days outside
Based off of BERT an abdomen X-ray is equivalent to - CORRECT ANSWERS 4 months outside
Based off of BERT a lumbar spine X-ray is equivalent to - CORRECT ANSWERS 1 year outside
, Image Gently Campaign - CORRECT ANSWERS A campaign launched in 2008 to raise awareness
about methods to reduce radiation dose during pediatric medical imaging exams.
What is an alpha particle? - CORRECT ANSWERS Two neutrons and two protons, the same as a
helium nucleus
What is a beta particle? - CORRECT ANSWERS a fast-moving electron given off by a nucleus
during radioactive decay
Pair production - CORRECT ANSWERS interaction between matter and a photon possessing a
minimum of 1.02 million electron volts of energy producing two oppositely charged particles, a positron
and a negatron
Photodisintegration - CORRECT ANSWERS An interaction between x-rays and matter
characterized by the interaction between a high-energy photon and the nucleus. The high-energy photon
strikes the nucleus; the nucleus absorbs all the photon's energy and then emits a nuclear fragment.
Somatic Damage - CORRECT ANSWERS biologic damage to the body of the exposed individual
caused by exposure to ionizing radiation
Skin Erythema Dose (SED) - CORRECT ANSWERS A measure of the amount of radiation a
person received to cause redness over the area measures in Gy
ICRP - CORRECT ANSWERS Leading international organization responsible for providing clear,
consistent radiation guidance through its recommendations on occupational and public dose limits.
Early tissue reactions - CORRECT ANSWERS - (8) Nausea, fatigue, diffuse redness of the skin,
loss of hair, fever, blood disorders, shedding of the outer layer of skin.
Late tissue reactions - CORRECT ANSWERS - (6) Cataract formation, fibrosis, organ atrophy, loss
of parenchymal cells, reduced fertility, sterility
