DESCRIPTION (provided by applicant): The overall objective of the proposed research is to design a relatively inexpensive kit suitable for sale which will enable the user to easily and accurately measure fluence of UV-C, particularly at 254nm, the most widely used wavelength for germicidal action. Though UV is widely used for sterilization of room air in hospitals and larger buildings, for sterilization of drinking water and waste water, there is currently no method for measuring fluence (irradiation from all directions, which determines the sterilization efficacy of UV), suitable for routine commercial use. Radiation from a single source may be adequately measured with currently available radiometers, but no method has been found to measure fluence by this means. Lack of a workable fluence measurement renders unfeasible the measurement of fluence for design verification or quality control of large air sterilization systems. The use of UV air disinfection is very likely to increase due to the threat of bioterrorism via airborne pathogens. The proposed kit will be of sufficient sensitivity to permit its use for personal dosimetry. Intense UV, some of which is in the "C" band, is widely used in industry for polymerization of coatings. This technology is recognized by the EPA as favored over solvent-based coatings because of the elimination of solvent fume air pollution.

描述（由申请人提供）：拟议的研究的总体目标是设计一个适合销售的相对廉价的套件，这将使用户能够轻松，准确地测量UV-C的通量，尤其是在254nm时，尤其是用于生物作用的最广泛使用的波长。尽管紫外线被广泛用于医院和较大建筑物中的房间空气灭菌（用于饮用水和废水的灭菌），但目前尚无测量通风量的方法（从各个方向进行照射，这决定了紫外线的灭菌功效），适用于常规商业用途。可以通过当前可用的辐射仪对单个源的辐射进行充分的测量，但是没有发现通过这种方式测量通量的方法。缺乏可行的通力测量，这会使大型空气灭菌系统的设计验证或质量控制的通量测量不可行。由于生物恐怖主义通过空中病原体的威胁，紫外空气消毒的使用很可能会增加。拟议的套件将具有足够的敏感性，以允许其用于个人剂量法。强烈的紫外线（其中一些在“ C”频段中）被广泛用于涂料的聚合。由于消除了溶剂烟气污染，因此EPA认为这项技术比基于溶剂的涂料所偏爱。
