New optical W-fiber Panda for fiber optic gyroscope sensitive coil
Technical Physics Letters, 2010Co-Authors: A. M. Kurbatov, R. A. KurbatovAbstract:Based on refractive index W-profile, two kinds of single-mode fibers are proposed: polarizing (bend type) and linear polarization maintaining (PM-fiber) with low losses (up to 0.35 dB/km). The polarizing W-fiber allows one to combine the dichroism in wide spectral range with opportunity to have almost any desirable mode field diameter (MFD). The PM-fiber low losses are essentially determined by fundamental mode tight packing in the guiding core. These fibers also can be Made Radiation resistant by replacing the germanium silicate core by nitrogen-doped core.

General Principles of Radiation Protection in Fields of Diagnostic Medical Exposure
Journal of Korean Medical Science, 2016Co-Authors: Kyung Hyun DoAbstract:After the rapid development of medical equipment including CT or PET-CT, Radiation doses from medical exposure are now the largest source of man-Made Radiation exposure. General principles of Radiation protection from the hazard of ionizing Radiation are summarized as three key words; justification, optimization, and dose limit. Because medical exposure of Radiation has unique considerations, diagnostic reference level is generally used as a reference value, instead of dose limits. In Korea, medical Radiation exposure has increased rapidly. For medical Radiation exposure control, Korea has two separate control systems. Regulation is essential to control medical Radiation exposure. Physicians and radiologists must be aware of the Radiation risks and benefits associated with medical exposure, and understand and implement the principles of Radiation protection for patients. The education of the referring physicians and radiologists is also important.

Multidimensional electron-photon transport with standard discrete ordinates codes
Nuclear Science and Engineering, 1997Co-Authors: Clifton Russell DrummAbstract:A method is described for generating electron cross sections that are comparable with standard discrete ordinates codes without modification. There are many advantages of using an established discrete ordinates solver, e.g. immediately available adjoint capability. Coupled electron-photon transport capability is needed for many applications, including the modeling of the response of electronics components to space and man-Made Radiation environments. The cross sections have been successfully used in the DORT, TWODANT and TORT discrete ordinates codes. The cross sections are shown to provide accurate and efficient solutions to certain multidimensional electron-photon transport problems. The key to the method is a simultaneous solution of the continuous-slowing-down (CSD) portion and elastic-scattering portion of the scattering source by the Goudsmit-Saunderson theory. The resulting multigroup-Legendre cross sections are much smaller than the true scattering cross sections that they represent. Under certain conditions, the cross sections are guaranteed positive and converge with a low-order Legendre expansion.

Health Effects of Low Level Radiation: When Will We Acknowledge the Reality?
Dose-response, 2007Co-Authors: Jerry M. CuttlerAbstract:The 1986 April 26th Chernobyl event was the worst nuclear power accident—it killed 31 people. Its significance was exaggerated immensely because of the pervasive fear of ionizing Radiation that has been indoctrinated in all of humanity. In reality, our environment includes Radiation from natural sources, varying widely in intensity, to which all living things have adapted. The effect of Radiation on organisms is primarily on their damage control biosystem, which prevents, repairs and removes cell damage. Low doses stimulate this system, while high doses inhibit it. So low doses decrease the incidences of cancer and congenital malformations; high doses have the opposite effect. Efforts by Radiation protection organizations to lower exposures to (human-Made) Radiation to as low as reasonably achievable (ALARA) provide no benefit. They only create inappropriate fear—barriers to very important applications of nuclear technology in energy production and medicine.
