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