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