Lead ct room door, Jinan open (certified), lead doors

 The main target of lead door: 1, ionizing radiation places: ★ diagnostic radiology: perspective, shooting, fault, dental, X-ray machines, CT protection. ★ Radiotherapy: simulators, after installed, C060 therapy machine, accelerators, X proton knife, gamma knife protection. ★ Interventional Radiology: cardiovascular imaging, interventional treatment protection. ★ nuclear medicine: Gamma Knife, CT, PET, and radionuclide therapy of protection. ★ other disciplines: body stone, bone densitometry, X-ray diffraction of protection. 2, electromagnetic radiation places: ★ room: radio, television, communication, navigation, radar transmitter room ★ workshop: metallurgy, electronics, chemical, paper, wood, food and food processing industries using high-frequency and microwave equipment for smelting, welding, heating, venting, sputtering, dry, pesticides, disinfection processes workshop ★ station: power generation and high-voltage power transmission stations and other places ★ Lab: electronic equipment and instruments commissioning area, military electronics equipment experiment station area, etc. ★ Other: Career Computer Use of premises (including: finance, accounting, savings, securities salesperson, cashier business, computer graphic design in the workplace, such as advertising design, construction, machinery, art, animation design, software development, and secretarial (typed copy) and a large, in arithmetic operations and place a small computer), electronic monitoring room, RF and microwave and other medical equipment rooms and so on. We generally will only lead glass recognize its radiation performance, in fact, there are many other useful lead glass, which is by its other structures to determine the following, we introduce other structures lead glass. Located in the glass surface A lead Pb2 + ion ct room door, only - · head by oxygen ion polarization, outward one end was a certain degree of metallic, which is bound to the surface of the glass has also undergone specific behavioral effects crystalline tetragonal unit cell structure PbO Pbc + ion by the oxygen ions polarization and deformation is more obvious. flaw lead in the crystallization process of the formation of the first gate of a unit cell of tetragonal PbO, the first four oxygen ions to the corpse b '+ ions move closer to the formation of poles. lead glass move closer to the lead after four oxygen ions ions, because lead ions "bipolar" and maintain a larger distance than the first four oxygen ions and lead ions. x-ray structure analysis of the data obtained before the four oxygen ions with lead ions distance of 2.3A, the distance after four oxygen ions and lead ions is 4.29 people, the latter is nearly twice the electric lead doors, reflecting the Pb2 + ion polarization and deformation Binary PbO-SiO2 glass PbO The concentration is small lead door, Pb: + from wide as Na20-SiO2 glass of Na + ions, like, from the outside network body function; large they PbO concentration apparently occurs Pb: + / corpse b: + balance, Pb true + ions [PbO :) groups into the network structure, and thus has been able to form a glass to the highest concentration of Pb "ions ionic radius ratio Pb:. + ions is much smaller, the field strength value divided by flute picks, belonging to the intermediate oxide (F ": fo.5 ~ 1) Xiang 7., Pb. outside '+ and Pb" ions in the glass network functionality Pbl + Pb' + network body intermediate oxide, lead glass if lead ions in a high concentration range also from outside the network body function, then into the glass in the nature of this concentration range is incomprehensible, because to 66gb (m01) PbO, in theory, a Si-O-Si have been disconnected from a bridge; Bray '2, for PbO content exceeding 50g6 (m01) of the high-lead glass also made a study of NMR experiments confirmed lead ions have four coordinated state. ct lead chamber door, Jinan open (certified), lead to open the door from Jinan Radiation Protection Technology Limited.
