BIOSA Technologies is a biotechnology company headquartered in Markham, Ontario, Canada. BIOSATechnologies current focus is on developing smart textiles and personal protective equipment to market andsell to hospitals, medical clinics, research laboratories, and other high radiation environments including wastemanagement workers world-wide. We are seeking expertise in radiation physics and radiation protection forhelp in designing the optimal PPE textile for radiation protection of workers in various industries.In this research project we will be investigating novel materials for PPE for radiation. We plan to conduct trialswith a variety of different innovative materials including high atomic number nanoparticles or crystals,graphene and hexagonal boron nitride (hBN) to determine if they can be used to protect from radiation. Theobjective being to obtain a sample fabric material that is light-weight, thin but provides optimal radiationattenuation, ideal for worker's everyday use and an alternative to traditional lead-base protective wear.Secondly, we plan to measure attenuation at different energies of photon radiation while we vary the thicknessof these materials in an attempt to determine which material will attenuate radiation to safe exposure levelswith the smallest thickness.This research will benefit people working in Canadian hospitals, medical clinics, aviation, researchlaboratories, Canadian waste management services, radioactive materials mining (ie Uranium Mining) andthose that work in nuclear industry by providing them protection from radiation exposure. The productdevelopment and manufacturing will contribute to the Canadian economy through national and internationalsales and the creation of new jobs.

BIOSA Technologies是一家总部位于加拿大安大略省万锦市的生物技术公司。biosattechnologies目前的重点是开发智能纺织品和个人防护设备，向医院、医疗诊所、研究实验室和其他高辐射环境（包括世界各地的废物管理工作者）推销和销售。我们正在寻求辐射物理和辐射防护方面的专业知识，以帮助设计适合各行业工人辐射防护的最佳PPE纺织品。在这个研究项目中，我们将研究用于防辐射PPE的新型材料。我们计划用各种不同的创新材料进行试验，包括高原子序数纳米颗粒或晶体、石墨烯和六方氮化硼（hBN），以确定它们是否可以用于防辐射。目的是获得一种轻质、薄但能提供最佳辐射衰减的样品织物材料，非常适合工人的日常使用，也是传统铅基防护服的替代品。其次，我们计划测量光子辐射在不同能量下的衰减，同时我们改变这些材料的厚度，试图确定哪种材料将以最小的厚度将辐射衰减到安全暴露水平。这项研究将使在加拿大医院、医疗诊所、航空、研究实验室、加拿大废物管理服务、放射性物质开采（即铀矿开采）和核工业工作的人受益，为他们提供免受辐射照射的保护。产品开发和制造将通过国内和国际销售和创造新的就业机会为加拿大经济做出贡献。
