What is the dose range delivered by Low Dose Rate (LDR) brachytherapy?

Low Dose Rate (LDR) brachytherapy is known for delivering a continuous low dose of radiation over an extended period. In the context of radiation oncology, LDR brachytherapy typically operates within a dose rate range of about 1 to 10 rads per hour.

The correct answer reflects the established range for LDR brachytherapy where the dose is delivered slowly enough to minimize damage to surrounding healthy tissue while effectively treating cancerous cells over time. This gradual delivery allows the body to repair itself between doses, which is a key advantage of LDR when compared to higher dose rate modalities.

Options that suggest a higher dose rate would be characteristic of higher dose rate (HDR) brachytherapy, which utilizes a different approach to deliver a much higher dose over a shorter time period, thus being suited for different treatment protocols. Hence, the selection aligns appropriately with the definition and implementation of LDR brachytherapy as it pertains to radiation safety principles and treatment efficacy in oncology.
