scholarly journals Photonic Crystal Fiber Sensor for X Ray Approximate Effective Radiation Dose

X-ray is electromagnetic wave pass through all human tissue and show tissue image by black and white, and the explosion for x ray in short treatment may cause cancer, Photonic crystal fiber used as detector for x- ray approximate effective radiation dose for human bone for spine x- ray 1.5 mSv which need 6month to repeat the exposure and extremity (foot, hand and etc.) x-ray 0.001 mSv need to 3 hours to repeat exposure , the change in x ray dose can be detected by measuring the change in wavelength shifting of laser 450nm which pass through photonic crystal fiber and effected by the emission of x-ray to record the small change in x-ray dose and save the human from radiation and this sensor is small compact and easy to use and have high sensitivity for x -ray used to measure the bone x-ray as its value lower than other x-ray used in others tissue. Index Terms— photonic crystal fiber, sensor ,x- ray, laser.

Abstract The radiation doses absorbed by major organs of males and females were studied from three types of dental X-ray devices. The absorbed doses from cone-beam computed tomography (CBCT), panoramic and intraoral X-ray machines were in the range of 0.23–1314.85 μGy, and were observed to be high in organs and tissues located in or adjacent to the irradiated area, there were discrepancies in organ doses between male and female. Thyroid, salivary gland, eye lens and brain were the organs that received higher absorbed doses. The organ absorbed doses were considerably lower than the diagnostic reference level for dental radiography in China. The calculated effective radiation doses for males and females were 56.63, 8.15, 2.56 μSv and 55.18, 8.99, 2.39 μSv, respectively, when using CBCT, the panoramic X-ray machine and intraoral X-ray machine. The effective radiation dose caused by CBCT was much higher than those of panoramic and intraoral X-ray machines.
