Radiation Safety Practice Exam

Which of the following is a method to enhance isotope excretion from the body?

1. Drinking high volumes of fluids

2. Increasing dietary fats

3. Reducing food intake

4. Using strong acidic drinks

The correct answer is: Drinking high volumes of fluids

Drinking high volumes of fluids is an effective method to enhance isotope excretion from the body. Increased fluid intake can help facilitate kidney function and promote urine production, allowing for the removal of radioactive isotopes and other harmful substances more efficiently. When the body is well-hydrated, there is an adequate volume of urine, which helps in flushing out contaminants, including any isotopes that may have been ingested or absorbed. In contrast, increasing dietary fats, reducing food intake, or using strong acidic drinks do not have the same beneficial impact on isotope excretion. High-fat diets could potentially slow down digestive processes and might not enhance renal excretion. Reducing food intake could lead to dehydration or might not facilitate the elimination of isotopes effectively. Strong acidic drinks might alter the metabolic pathways, but they don't provide the hydration necessary for improving the excretion process as well as increased fluid intake. Therefore, drinking ample fluids plays a crucial role in promoting isotope excretion efficiently.
