The exposure of nuclear medicine technologists to airborne radiocontaminants is generally far below the compliance limits. Most of the contamination is external rather than internal deposition. Higher contamination levels approaching the allowable limits are rare. Personal respiratory protection is unwarranted and may have undesirable impressions on patients undergoing lung scanning. Exposures are well controlled by suitable work practices that are in keeping with as low as reasonably achievable (ALARA) principles.
核医学技术人员暴露于空气中放射性污染物的情况通常远低于合规限值。大多数污染是外部污染而非内部沉积。接近允许限值的较高污染水平很少见。个人呼吸防护没有必要，而且可能会给接受肺部扫描的患者留下不良印象。通过符合合理可行尽量低（ALARA）原则的适当工作方法，可很好地控制暴露情况。
