원격 컴퓨팅 Invisible rays such as X-rays, gamma rays, neutron, beta rays, etc., can 몽키VPN penetrate surfaces and pose radiation hazards. These ionizing radiations are used/emitted from 가상 윈도우 컴퓨터 hospitals, nuclear power plants, particle accelerators, industrial radiography, etc. It is important 마케팅스토어 to protect the public, patients, and the environment from harmful radiation.Radiation shielding 무료콜백문자 materials are used to prevent the hazardous spread of radiation. The thickness DB추출기 of the radiation shield varies with respect to the energy, type of 앱솔루션 radiation and attenuation characteristics of the shield. For example, 1 to 2.3mm 마케팅 VPN thick lead sheets are used on the wall of X-ray rooms, CT 마케팅프로그램 scanner rooms, etc., to shield X-rays. But 450 mm thick lead or DB프로그램 2300 mm wide concrete is used to build 10 MeV radiotherapy bunkers.The 프로그램 lightweight (2.3g/cc) and heavyweight (>2.6 g/cc) concretes are commonly used to build 영업디비 radiation shielding structure in radiotherapy bunkers, nuclear power plants, sterilization plants, etc. 채팅솔루션 But these have their inherent disadvantages like using up space, being expensive, 앱스토어 검색 non-replenishable and thermally unstable.Red mud is a hazardous alumina industry waste that 챗솔루션 is very alkaline and has heavy element leaching. Globally, 170 million tonnes 스마트폰콜백 of red mud are generated annually and is left unused in the 콜백문자서비스 disposal plants due to inadequate technologies for its large-scale utilization. Currently, only 마케팅 전문가 3- 4 % of red mud is used to fabricate useful products. 어플제작 The rest is getting accumulated in the disposal plants and possess a 개발회사 serious threat to the public, environment, and wildlife (Figure 1). Figure 1: Disposal 마케팅기업 of red mud into the red mud pond CSIR-AMPRI has developed the technology 게임IP to convert the iron-rich red mud into X-ray, gamma-ray and neutron shielding 마케팅 프로그램 materials. It is a green process and is economically viable. A certain 채팅앱개발 weight percentage of BaSO4 and kaolin clay binder is added to the 실행사 red mud to increase its X-ray attenuation characteristics and mechanical strength, respectively.The 일반채팅 X-ray shielding tiles were fabricated by mixing appropriate proportion of red mud, 온라인 마케팅 BaSO4 and kaolin clay powder in a ball mill. The red mud:BaSO4:kaolin 게임 VPN compound mixtures were wet ground with water, and then green tiles were 재능마켓 made by applying ≈530 kg/cm2 pressure. The developed tiles were dried in 프로그램스토어 a hot air oven at 90°C and then sintered between 900 - VPN 1150°C in ambient conditions (Figure 2a).The developed tiles possess the breaking strength VPN 서비스 of 1880 N and the modulus of rupture of >25 N/mm2. Nearly 마케팅 스토어 12 - 15mm thick tile possess the attenuation equivalent to 2 mm 플레이스토어 검색 lead at 100 kVp. Moreover, no heavy metals were found to leach APP 개발회사 from the tiles above the permissible limit.Joint free X-ray shielding tiles (2500 가상 컴퓨터 ft2) were fabricated and demonstrated in two X-ray diagnoses, one CT scanner 아이피 변경 and one Cath Lab of M/s Saideep Healthcare and Research Pvt Ltd., 채팅어플제작 Ahmednagar, Maharashtra. The X-ray installations are currently in operation (Figure 2b). Figure 2: 영업 (a) joint free X-ray shielding tiles made using red mud and (b) 마케팅프로그램 The CSIR-AMPRI tile in use in the Cath lab of M/s Saideep 앱마케팅 Healthcare and Research Pvt Ltd The technology for the fabrication of “Lead-Free X-ray 마케팅 서비스 Shielding Tiles” was transferred to M/s Prism Johnson Ltd., on 10/06/2019 at 프로그램 스토어 CSIR, New Delhi. CSIR-AMPRI and M/s Prism Johnson Ltd have worked together 앱개발 and solved various problems like white efflorescence, cracking, melt-sticking and attenuation, which 문자명함 evolved during upscaling of this technology from the lab to the industrial 영업문자 scale. All the problems were solved, and X-ray shielding tiles were made 자동문자 on a pilot scale on September 2021 (Figure 3). The product will 앱개발 be launched soon. The 12 -15 mm thick tiles possess the attenuation 마케팅프로그램 of 2 mm lead at 100 kVp and have sufficient mechanical strength. 마케팅IP The developed tiles are cheaper than lead and barite boards. Figure 3: Joint 자동콜백 free X-ray shielding tiles made in pilot scale The developed tiles are suitable 가상 윈도우 for shielding diagnostic X-rays. However, it requires a thick shield to attenuate 개발업체 very high energy X-rays, gamma rays and neutrons due to their porosity 콜백문자 and less density.CSIR-AMPRI has also recently developed gamma-ray shielding blocks by hot 스마트문자 compacting red mud. The density of the shield is found to be NEW DB double than that of the radiation shielding blocks fabricated through the conventional 화상채팅 ceramic route. In many places, both the neutron and gamma-ray shielding materials 앱부스터 are required as neutrons are generated as secondary radiations. These shields are VPN capable of shielding both the neutron as well as high energy X- VPN 서비스 and gamma rays.This technology can promote the large-scale utilization of red mud 채팅어플 and reduce the usage of toxic lead, primary mining, deforestation, and environmental pollution.Dr. Shabi Thankaraj Salammal Dr. Deepti Mishra Dr. Mohd.
