CORRECT!!!
Q: What do we call the energy and particles released from an unstable atomic
nucleus during its breakdown?
A: Nuclear radiation
Q: How is radioactive (nuclear) decay best described?
A: It's the process where an unstable nucleus emits energy to reach a more stable
state.
Q: Which type of radiation particle loses energy rapidly through ionization, has
limited travel distance, and can’t pass through paper?
A: Alpha particle
Q: What does the unit REM measure?
A: The potential biological impact or health risk from radiation exposure.
Q: What is the special unit used to measure radiation exposure in the air?
A: Roentgen
Q: RADIAC devices that work using ionization are classified into three main types
based on what factor?
A: Their operating voltage levels
, Q: What type of radiation exposure occurs in a short time and typically involves
high doses?
A: Acute exposure
Q: What is the electrical charge of an electron?
A: Negative
Given that protons are red, neutrons are blue, and electrons are gold, which atom is
an ion? - ANSWERS✔✔Pick the one with a different number of electrons and
protons
What is RADIAC equipment used for? - ANSWERS✔✔To detect or measure
ionizing radiation
What are the two most common operating principles for modern RADIAC
instruments - ANSWERS✔✔Ionization & Scintillation
Which category of biological effects of ionizing radiation can affect an embroyo? -
ANSWERS✔✔Embryological
Are these atoms isotopes? - ANSWERS✔✔Yes, but look at the picture dummy
How do RADIAC instruments that use the operating principle of scintillation
detect ionizing radiation? - ANSWERS✔✔They measure the light energy released
when a special phosphorescent material is struck by ionizing radiation
Which types of ionizing radiation are primarily an external hazard? -
ANSWERS✔✔Gamma rays & X-Rays
