Question

When working with or near radiation, which of the following statements is correct?

a) Wear dark clothing for protection
b) Increase exposure time for better immunity
c) Minimize time, maximize distance, and use shielding
d) Consume antioxidants before exposure

Answer 1

The correct approach to working safely with radiation is to minimize exposure time, maximize distance from the source, and use effective shielding to protect against radiation.

Step-by-step explanation:

When working with or near radiation, the correct approach to minimize risk is c) Minimize time, maximize distance, and use shielding. This is because:

• Keeping minimum possible time in the radiation environment reduces exposure.
• Maintaining as much distance from the radiation source as possible is essential since the intensity of radiation drops inversely proportional to the square of the distance.
• Using effective shielding can block or absorb radiation, thereby reducing exposure. Materials such as lead are commonly used for this purpose.

It is essential to recognize that the safest amount of radiation exposure to the human body is zero. In situations where exposure cannot be completely avoided, these measures are the best practice for reducing dose and ensuring safety.

Answer 2

The correct statement for working with radiation is to minimize exposure time, maximize distance from the source, and use proper shielding to protect oneself. These methods help reduce radiation exposure, as complete avoidance of ionizing radiation is not possible.

Step-by-step explanation:

When working with or near radiation, the correct statement regarding safety measures is: minimize time, maximize distance, and use shielding. To protect yourself from the dangers of radiation exposure, it's essential to:

• Keep minimum possible time in the radiation environment, as less time means less exposure.
• Maintain as much distance from the radiation source as possible. The intensity of radiation decreases inversely proportional to the square of the distance from the source.
• Utilize shielding between you and the source of radiation. The more the shielding, the less the exposure you receive.

The safest amount of radiation to the human body is zero. However, since it is impossible to completely avoid exposure to ionizing radiation, these practices are the best ways to minimize exposure and maximize safety.
