Collection and usage attributes

Guide for use:Help on this term

The brachytherapy dose rate refers to the amount of radiation delivered by the source in Grays per hour (Gy/h).

CODE 1   Low dose rate (LDR)

Brachytherapy with a radiation source that emits up to 2 Gy/h.

CODE 2   Medium dose rate (MDR)

Brachytherapy with a radiation source that emits 2 Gy/h to 12 Gy/h.

CODE 3   High dose rate (HDR)

Brachytherapy with a radiation source that exceeds 12 Gy/h.

CODE 4   Pulsed dose rate (PDR)

Brachytherapy involving short pulses of radiation, which simulates an overall rate equivalent to LDR.
