What is the effect of increased exposure time on the radiation dose received?

Increased exposure time directly correlates with an increase in the radiation dose received. This relationship is based on the fundamental principle that the longer a person is exposed to a radiation source, the greater the amount of radiation they will absorb. In dental radiography, for instance, if the exposure time is extended, the number of x-ray photons emitted during that time also increases, leading to a higher cumulative dose of radiation.

Understanding this concept is essential for radiation safety in dental practices, as it emphasizes the importance of optimizing exposure times to minimize patient risk while achieving the necessary diagnostic quality in imaging. Proper techniques and protocols can help manage exposure duration effectively, ensuring that patients receive only the necessary amount of radiation for their imaging needs.
