Question

Which of the following examinations is/are likely to increase personnel dose?

1) 1 only
2) 2 only
3) 1 and 2 only
4) 1, 2, and 3

Answer 1

The question pertains to activities that could result in heightened radiation exposure for personnel, particularly in medical or industrial contexts dealing with ionizing radiation. Geiger counters, scintillators, and dosimeters are devices used to measure radiation levels, and a problem-solving strategy involves confirming exposure and identifying the radiation dose calculations.

Step-by-step explanation:

The question 'Which of the following examinations is/are likely to increase personnel dose?' refers to procedures that may expose workers to higher doses of ionizing radiation. Such examinations could potentially involve medical imaging technologies or radiological procedures that require individuals to be in proximity to radioactive materials or emissions. Radiation exposure could occur in industries or medical settings where radiation is used either for diagnostic or therapeutic purposes. The types of work that can cause an increase in personnel radiation exposure include handling radioactive materials, operating x-ray machines, performing fluoroscopic procedures, or working in environments where there is residual radioactive contamination.

To calculate the radiation dose that personnel might receive, a typical problem-solving strategy outlined in the information provided would be to first confirm the exposure to ionizing radiation (Step 1) and then identify what needs to be determined, such as the dosage in millisieverts (mSv) or grays (Gy) (Step 2). For instance, dealing with x-rays, neutron exposure, or radiation from radioactive potassium in the body could all lead to different radiation doses.

Measurement devices such as Geiger counters, scintillators, and dosimeters are commonly used to quantify radiation levels and ensure that exposure does not exceed safety guidelines. Understanding the conversion between Sv and Gy, and the relative biological effectiveness (RBE), is also crucial. Doses are categorized as low (<0.1 Sv), moderate (0.1 to 1 Sv), or high (>1 Sv), with increased risks associated with higher doses.
