What is the threshold under which there is no risk of DNA damage?
- A.
0.5Sv
- B.
No level is safe
- C.
100mSv
- D.
1gY
Correct Answer
B. No level is safeExplanation
The correct answer is "No level is safe." This means that there is no threshold level of radiation exposure that can be considered completely risk-free in terms of DNA damage. Even very low levels of radiation exposure can potentially cause harm to DNA and increase the risk of mutations and other genetic damage. Therefore, it is important to minimize exposure to radiation as much as possible to reduce the risk of DNA damage and associated health effects.Rate this question:

Which category is a bigger issue with regard to occupational hazards?
- A.
Stochastic
- B.
Non-stochastic
- C.
Deterministic
Correct Answer
A. StochasticExplanation
Stochastic hazards refer to those that occur randomly or by chance, making them unpredictable. Non-stochastic hazards, on the other hand, are those that have a direct cause and effect relationship and can be identified and controlled. In terms of occupational hazards, stochastic hazards are generally considered a bigger issue because their random nature makes it difficult to anticipate and prevent them. Non-stochastic hazards, although still important, can often be mitigated through proper risk assessment and control measures. Therefore, the correct answer is stochastic.Rate this question:

How much more radiation exposure do interventional cardiologists get when compared to diagnostic radiologists?
- A.
15-20x
- B.
1.5x
- C.
2-10x
- D.
15x
Correct Answer
C. 2-10xExplanation
Interventional cardiologists perform procedures that involve higher levels of radiation exposure compared to diagnostic radiologists who primarily interpret medical images. This is because interventional cardiologists are directly involved in procedures such as angioplasty and stent placement, which require the use of fluoroscopy and longer exposure times. On the other hand, diagnostic radiologists mainly focus on interpreting images and do not have the same level of direct radiation exposure. Therefore, interventional cardiologists typically receive 2-10 times more radiation exposure than diagnostic radiologists.Rate this question:

Cataracts
- B.
Thyroid Disease
- C.
Nose Bleeds
- D.
Cardiovascular Changes
- E.
Tooth Aches
Correct Answer(s)
A. Cataracts
B. Thyroid Disease
D. Cardiovascular ChangesExplanation
Exposure to low level radiation can lead to various health risks. Cataracts, a condition characterized by clouding of the lens of the eye, can be caused by radiation exposure. Thyroid disease, such as hypothyroidism or thyroid cancer, is also a significant risk associated with radiation exposure. Additionally, cardiovascular changes, such as an increased risk of heart disease or stroke, can occur due to radiation exposure. However, nose bleeds and tooth aches are not commonly associated with low level radiation exposure.Rate this question:

Without protection how much radiation does an average interventional cardiologist get to their brain?
- A.
500mSv
- B.
1Sv
- C.
100mSv
- D.
250mSv
Correct Answer
A. 500mSvExplanation
An interventional cardiologist who does not have any protection is exposed to an average of 500mSv of radiation to their brain. This level of radiation exposure is considered significant and can potentially have harmful effects on the health of the cardiologist. It is important for interventional cardiologists to wear proper protective gear and follow safety protocols to minimize their radiation exposure.Rate this question:

Which of the following are non-radiation causes of cataracts?
- A.
Obesity
- B.
Age
- C.
Diabetes
- D.
Reading small print
- E.
Corticosteroid Treatment
Correct Answer(s)
B. Age
C. Diabetes
E. Corticosteroid TreatmentExplanation
Cataracts can be caused by various factors, including non-radiation causes. Age is a well-known risk factor for cataracts, as the lens of the eye naturally becomes less transparent and more rigid with age. Diabetes is also associated with an increased risk of cataracts, likely due to the changes in blood sugar levels that can affect the eye's lens. Corticosteroid treatment, which is commonly used to reduce inflammation, can also lead to cataract formation. Obesity and reading small print, on the other hand, are not mentioned as non-radiation causes of cataracts.Rate this question:

Functional changes resulting in hypo or hyperthyroidism can be the result of radiation exposure.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Functional changes in the thyroid gland can occur as a result of radiation exposure. Radiation can damage the cells of the thyroid gland, leading to either hypo or hyperthyroidism. Hypothyroidism occurs when the thyroid gland is underactive and does not produce enough thyroid hormones, while hyperthyroidism occurs when the thyroid gland is overactive and produces an excess of thyroid hormones. Therefore, the statement "Functional changes resulting in hypo or hyperthyroidism can be the result of radiation exposure" is true.Rate this question:

What are the two most effective methods for controlling occupational exposures?
- A.
Education
- B.
Source reduction
- C.
Implementation of engineering or administrative controls that distance the individual from the source
- D.
Dose measurment
Correct Answer(s)
B. Source reduction
C. Implementation of engineering or administrative controls that distance the individual from the sourceExplanation
The two most effective methods for controlling occupational exposures are source reduction and implementation of engineering or administrative controls that distance the individual from the source. Source reduction involves eliminating or minimizing the source of the exposure, while engineering or administrative controls focus on creating physical barriers or implementing policies to reduce exposure. These methods are considered effective because they target the root cause of the exposure and prevent or minimize it, leading to a safer work environment.Rate this question:
