Abstract
Brachytherapy is a form of radiation therapy that uses small radioactive sources placed a short distance from the treatment area. The steep dose gradient with these sources allows a high dose to be delivered to the target while sparing the surrounding normal tissue.

Notes
- 1.
From the Greek word ‘brachy’ meaning short or close.
- 2.
Or alternatively as low as reasonably achievable (ALARA).
- 3.
For the first example, the dose rate behind the screen is 2 μSv/h, so ten procedures is equivalent to three days of natural background exposure.
