Question 1
What type of report is the dose equivalent to the lens of the eye from external exposure?
Correct Answer:
Eye dose equivalent
Explanation:
When protecting people from radiation, different dose quantities are used to reflect how different parts of the body respond. The lens of the eye is especially sensitive, so its exposure is tracked separately from the rest of the body. The dose to the lens from external exposure is reported as the eye dose equivalent, a specific quantity that represents the radiation dose reaching the lens itself. This is the metric used in regulations and records to assess and limit cataract risk. Other body parts have their own dedicated measures, such as the deep dose equivalent for the whole body, but the lens gets its own eye-focused dose equivalent.
Question 2
For light elements, meaning those with fewer protons, the appropriate ratio is what?
Correct Answer:
1:1
Explanation:
The main idea is that light, stable nuclei have roughly equal numbers of neutrons and protons. This neutron-to-proton balance (N/Z) near 1:1 provides enough strong-force binding while keeping the electrostatic repulsion between protons from getting too large. For these small nuclei, adding extra neutrons isn’t needed to stabilize them, so N approximately equals Z. As nuclei become heavier, more neutrons are needed to offset increasing proton repulsion, so the ratio grows above 1. Therefore, for light elements the appropriate ratio is 1:1.
Question 3
Which statement best defines 'occupational dose'?
Correct Answer:
The dose received by an individual in the course of their employment
Explanation:
Occupational dose is the radiation dose that a worker receives as part of their job duties. This exposure is specific to people who are employed and may come into contact with radiation in the workplace, and it’s what safety programs monitor to keep workers within regulatory limits and minimize risk through practices like ALARA and using dosimeters. The other contexts describe different exposures: dose to the general public is exposure outside the workplace, patient dose is the dose a patient gets during medical imaging or treatment, and the theoretical/planning dose is an estimate used for designing facilities or procedures, not the actual exposure a worker experiences.
Question 4
The amount of energy absorbed per unit weight of the organ or tissue is called what?
Correct Answer:
Absorbed dose
Explanation:
The main concept is energy deposition in tissue per unit mass from radiation. That quantity is called absorbed dose. It measures how much energy the tissue actually absorbs, which is what drives potential biological effects. The unit is the gray, defined as one joule of energy absorbed per kilogram of tissue. In contrast, exposure refers to radiation in air and isn’t about energy deposited in tissue, while activity is the rate of radioactive decay. So absorbed dose is the precise term for the energy per unit mass absorbed by tissue.
Question 5
What subatomic particles are found orbiting the nucleus in the electron cloud on paths known as shells?
Correct Answer:
Electrons
Explanation:
Electrons are the subatomic particles that orbit the nucleus in the electron cloud. The nucleus stays at the center with protons and neutrons, while electrons occupy surrounding energy levels called shells (or orbitals) and are held in by the electrostatic attraction to the positively charged nucleus. Quarks are the smaller constituents inside protons and neutrons, not free-floating in orbit, and neutrons themselves reside in the nucleus rather than orbiting. So the particles found orbiting the nucleus are electrons.
