照護接受體內放射治療（Internal radiation/brachytherapy）的病人，必須嚴格遵守放射防護原則：時間（Time）、距離（Distance）、屏蔽（Shielding）。其中「距離」是減少輻射曝露最有效的原則，因為輻射劑量與距離的平方成反比。護理師應盡量減少停留時間，並保持至少 6 英尺的距離。此外，孕婦嚴禁照護此類病人，以保護胎兒健康。
Radiation safety follows the principles of time, distance, and shielding, with distance being the most effective method to reduce exposure. Maintaining at least 6 feet from the source minimizes radiation dose because intensity decreases with the square of the distance.
