Ventilation and Air Conditioning Design for Nuclear Medicine Department of General Hospital

核医学科室按放射性核素活性的高低分为控制区,监督区和非限制区,每个区设置不同的功能用房。采取建筑围合,局部通风柜以及独立的通风空调系统从源头减少或隔断放射源的辐射。结合实际工程,给出室内设计参数,气流流向,室内压力设定值以及排风口设置位置,并给出了典型核医学空调系统原理图以及压力控制策略。

Nuclear medicine departments are divided into control zones,supervision zones and non-restricted zones according to the level of radionuclide activity.Each zone has different functional rooms.Building enclosure,local ventilation cabinet and independent ventilation and air conditioning system are adopted to reduce or isolate radiation from the source.Combining with practical engineering,the indoor design parameters,air flow direction,indoor pressure setting value and exhaust outlet setting position are given,and the schematic diagram of typical nuclear medicine air conditioning system and pressure control strategy are given.
