“…The detectors were then taken out, rinsed with distilled water, and dried to be prepared for track reading under an optical microscope. The optical microscope (Pro.Way made in China) was equipped with a 5-megapixel camera developed with LED light instead of tungsten light, which has proven to be of high efficiency in terms of clarity of vision and track number [8,9]. It is able to give magnification by an objective (4X, 10X, 40X, and 100X) and two eyepieces (40X) to count the number of tracks.…”

Radon and its daughters are of the natural radioactive decay of the uranium series. Exposure to radon gas leads to lung cancer, so the risks are significantly higher for smokers than for non-smokers. Therefore, the risk of radon increases for both active and passive smokers. The radioactivity of alpha particles emitted by radium 226, the main source of radon 222, has become harmful because its prevalence and inhalation increase with increased smoking. In this study, a CR-39 detector was used to measure radon, radium, and uranium concentrations and then calculate risk parameters in seven cigarette-smoking females in vitro study of human blood samples, and three normal females with no actual and passive cigarette smoking. The radon concentrations in blood samples varied from 147.36±0.08 Bq/kg to 659.92±0.04 Bq/kg with an average of 316.83±150.42 Bq/kg, the radium concentration varied from 13.55±0.27 Bq/kg to 60.70±0.13 Bq/kg with an average value 29.05±13.84 Bq/kg, and uranium concentration varies from 11.89±0.29 ppm to 53.23±0.14 ppm with an average value 25.47±12.13 ppm. The annual effective dose ranged from 4.42±0.48 to 12.57±0.28 mSv/y with average value of 8.35±3.10 mSv/y. The annual risk cases of lung cancer varied from 79.50±.0.11 to 226.26±0.07 with an average value of 150.22±55.78 per million people. The results deal with the radioactive effect of female cigarette smokers as a risk factor for lung cancer. Most of the results exceed the permissible international limits. Hence, human health and their life are at risk of radioactivity resulting from cigarette smoking that is concentrated in the blood of female smokers examined in this work.

“…Enhancement of images is an important area in digital image [1][2][3]. This manipulation includes low lightness and contrast, as is often the case in hazy images, in which the lack of contrast plays an important role in many applications.…”

The use of hazy images is amongst the fastest ways to identify natural resources. Aerial photography has overcome the obstacles faced in land areas, such as rugged areas, swamps and sand dunes. It has important applications in tracking and monitoring studies during wars and peace. However, aerial images often suffer from the lack of contrast due to dust and pollutants. Therefore, this study attempts to improve aerial images by modified dark channel prior (DCP) and adaptive histogram equalisation (AHE) algorithms with YIQ. The images are first improved through DCP and then converted into YIQ colour space that saves the chromatic compounds (IQ). The lighting component comes out after improving the original aerial image via the stretch technique and AHE. Afterwards, all the compounds are merged, and reverse transformation is performed. The proposed method for improving aerial photographs was compared with several other methods. By analyzing the results, the proposed method obtained the best measures of quality, including an entropy value of (7.771), an average gradient value of (14.207) and a naturalness image quality evaluator value of (3.700).

“…Image processing is concerned with performing operations on images for improvement according to specific criteria or for extraction of specific information [1] [2]. Images, such as dusty ones, commonly suffer from a decrease in light and contrast [3]; however, such a decrease plays an important role in aerial images.…”

Improvements in aerial images have an important role, given the increase in dust storms due to global warming and climatic changes. Apart from improving aerial images, image enhancement is important in many applications, such as tracking and monitoring studies during wars and for the environment. However, aerial images often suffer from a lack of contrast due to dust and pollutants. In this study, we propose a perceptual dark channel prior (PDCP). In this method, the light value (Y) is improved by using stretch and perceptual color space, and then the chromatic compounds (CbCr) are improved by dark channel prior (DCP). The quality measures lightness order error (LOE), entropy, and color-fullness metrics (CM) and then compares these with the improved methods (DCPMV, YCBCR, MLA, SEA, DCP, and IEIF) to determine the method efficiency. Results show that the proposed PDCP effectively enhances the aerial images better than other methods, because owning it the average are LOE (194.096), EN (7.361), and CM (39.403).
