Potential leakage of 133 xenon is a covert, insidious facet of ventilation imaging procedures. Airborne xenon is often unrecognized and, consequently, unmanaged. The presence of xenon in air is usually unrecognized because it is not sought! Ventilation imaging procedures should incorporate safeguards for the protection of people against the internal exposure of radiation due to the inadvertent release of xenon gas in the air. Protective measures include surveillance by area survey and air monitoring, maintenance of equipment, establishment and preservation of safety procedures, and management of airborne contamination. The need to follow the accepted health physics objective to reduce radiation exposure of humans to the lowest practicable level is reaffirmed!
133氙的潜在泄漏是通气成像程序中一个隐蔽、潜伏的方面。空气中的氙气往往未被识别，因此也未得到管理。空气中氙气的存在通常未被识别，因为人们没有去寻找它！通气成像程序应包含保障措施，以保护人员免受因空气中氙气意外释放而导致的辐射内照射。保护措施包括区域监测和空气监测、设备维护、安全程序的制定和保存以及空气中污染物的管理。再次强调需要遵循公认的健康物理学目标，将人类的辐射暴露降低到可行的最低水平！
