How does increasing time spent near a radiation source affect dose?

Increasing the time spent near a radiation source directly affects the dose received because exposure to radiation is cumulative; the longer an individual is in proximity to the source, the higher the total dose they will receive. This relationship is a fundamental concept in radiation safety and dose management, based on the principle that radiation exposure contributes to the overall dose in a linear fashion over time.

This means that if a person remains near a radiation source for an extended period, they absorb more radiation, which increases the measurable dose. It is critical for radiation workers to understand this principle to effectively implement safety measures, such as limiting time near sources of radiation to minimize exposure and protect their health.

In contrast, the other answers do not accurately reflect the relationship between time and radiation exposure. Thus, the key takeaway is the importance of managing time to mitigate radiation dose effectively.
