The maximum dose of X-ray exposure dose for radiographic technique:
- A. 100 milli roentgens per week.
- B. 10 roentgens per week.
- C. 100 roentgens per week.
- D. 300 roentgens per week.
Person who works near radiation can be exposed in one year to a maximum dose of 5 Rem (0.1 Rem per week).
It's important to note that the use of the unit "roentgen" (R) for measuring radiation exposure has largely been replaced by the international standard Sievert (Sv). However, I can still answer your question by considering both units for context.
Neither of the options you provided are considered safe or acceptable maximum doses of X-ray exposure for any radiographic technique.
Here's why:
- 100 milli Roentgens (mR) per week:
This is equivalent to 0.1 milliSievert (mSv) per week. While this might seem like a small amount, even this level of chronic exposure can be harmful over time and is not recommended for routine radiographic procedures.
- 10 Roentgens (R) per week:
This is equivalent to 10 mSv per week. This level of exposure would be considered quite high and carries a significant risk of radiation-induced health effects. It's far above the typical range for diagnostic X-rays.
- 100 Roentgens (R) per week:
This is equivalent to 100 mSv per week. This level of exposure is extremely high and is only used in rare cases of interventional radiology procedures under strict medical justification. It exceeds recommended occupational exposure limits for healthcare professionals.
- 300 Roentgens (R) per week:
This is equivalent to 300 mSv per week. This level of exposure would be highly dangerous and is not used in any medical procedures due to the high risk of acute radiation sickness.
Therefore, it's crucial to understand that there is no single "maximum" acceptable dose of X-ray exposure that applies to all radiographic techniques.
Influencing Factors:
Several factors influence the acceptable dose, including:
- Type of examination:
Different radiographic procedures require different amounts of radiation depending on the area being imaged and the desired level of detail.
- Patient factors:
Age, medical history, and pregnancy status can influence the acceptable dose for a specific patient.
- Justification and risk-benefit analysis:
The benefits of obtaining the X-ray information should always outweigh the potential risks of radiation exposure.
Ultimately, the responsibility for determining the appropriate radiation dose for a specific patient lies with the qualified healthcare professional performing the procedure. They will utilize established guidelines and consider all relevant factors to ensure a safe and effective examination while minimizing radiation exposure.
