Design and construct optimum dosimeter to detect airborne radon and thoron gas: Experimental study

Evaluation of boron concentration in water samples of Al-Diwaniya Governorate (in Iraq) using ICP/OES Techniques

“…The concentration of boron in the earth's crust has been estimated to be <10 ppm, but concentrations as high as 100 ppm can be found in boron-rich areas [2]. It does not appear on the earth in elemental form but is found in combined state as borax, boric acid, tourmaline, colemanite, kernite, ulexite and borates [3][4][5][6].Boron deficiency is much more common in crops that are grown in soil that have higher amount of free Carbonates, low organic matter, and high pH [7]. Boric acid, borates and per borates can introduced to environment as these have been used in mild antiseptics, cosmetics, pharmaceuticals [8].…”

A study of indoor radon levels in Iraqi Kurdistan Region, Influencing factors and lung cancer risks

“…1. Passive radon dosimeter geometry is a closed-opened chamber into which radon diffuses, and it has been calibrated by Ismail and Jaafar [9]. The schematic diagram of the chamber is shown in Fig.…”

Design new detection technique for deposition of radon's daughter onto human blood samples

“…CR-39NTDs with the density of 1.31 g/cm 3 , thickness of 700µm cut into (1×1.5) cm engraved code ,and its efficiency 80.1±1.23% [11 ]. Blood samples (2.5 ml) collected by venipuncture into heparin zed syringes for 20 male and 20 female (20-52 years old).…”

“…After 28 days of exposure, radon concentration is saturated. Second part (B), included systematic of human blood and CR-39NTDs exposure to radon gas, radiation dosimeters (type VICTOREEN), Thermometer and the radon chamber (high =7cm, diameter 6 cm) [11]. Third part (C), include RAD7 that used to measure radon concentration during the period of exposure.…”
