“…There are three natural isotopes of the radioactive element radon 222 Rn originate in the 238 U decay series with a half-life of 3.82 days, thoron ( 220 Rn) is in the 232 Th chain with a half-life of 55.6 s, actinon ( 219 Rn) is in the 235 U series with a half-life of 4 s (IAEA, 2003). Radon can be considered to be of the most dangerous radioactive elements in the environment (Mansur et al, 2005). The most important mechanism of exposure is the inhalation of the short lived decay products of the principal isotope, 222 Rn with indoor air.…”

Solid state nuclear track detectors are used in very broad fields of technical applications and successfully applied in different areas of environmental physics and geophysics. Radon concentration and surface exhalation rate for phosphate samples from El-Sebaeya and Abu-Tartur, Egypt, were measured using nuclear tracks detectors from types CR-39 and LR-115. The average values of radon concentration are 12711.03 and 10925.02 Bqm À3 in El-Sebaeya area using CR-39 and LR-115 detectors, respectively. Also the average values of radon concentration are 15824.16 and13601.48 Bqm À3 in Abu-Tartur area using CR-39 and LR-115 detectors, respectively. From the obtained results we can conclude that the average values of radon concentration in Abu-Tartur are higher than El-Sebaeya. The present study is important to detect any harmful radiation which, can be used as reference information to assess any changes in the radioactive background level in the surrounding environment.

In this work, measurements of indoor radon concentrations were completed for selected dwellings in Baghdad governorate using DURRIDGE RAD7 detector. The spectra measured by this detector demonstrated that, the radon concentrations were changed from 89 Bq/m 3 (Hay Ur district) to 191 Bq/m 3 (Al-Mansour district) with an average value of 123.3±24.3 Bq/m 3 which is below the recommended range (200-300 Bq/m 3 ) given by (ICRP, 2009). All other studied parameters such as EP, PAEC, AED and CPPP their values were less than or corresponding to the allowed worldwide average values.

“…All types of building materials such as sand, gravel, concrete, brick, and granite contain potassium, uranium, thorium, and their progenies; they generate a direct radiation exposure (Cetin, et al, 2012). Previous studies reported that the radon and other natural radionuclide traces emanate of sand and gravel (raw building materials) (Banman, et al, 1982;Mansoor, et al, 2005).…”

The samples, sand and pebble (Sediment River), were collected from their selling places in Sulaymaniyah city, Iraq. Sand and pebble emanate each of 238 U, 232 Th, 40 K, and radon naturally. The radon concentration in the air (C o ) and gamma-specific activity (A s ) of the samples were measured using passive detectors (CR-39) and gamma spectrum analyzer (3 × 3 NaI (Tl) connected to digital spectrum analyzer), respectively. The mean value of the C o ± deviation of the investigated samples was 176.5 ± 6.9 Bq/mᵌ, which is lower than the worldwide value of 300 Bq m − ᵌ reported by the IAEA. However, an anomaly in C o value was found in Tanjaro (Sand) sample. The mean value radon mass exhalation rate (E M ) was 10.9 ± 0.5 μB q /kg/h. The second part of the measuring is the gamma-specific activities (A s ) of each 226 Ra, 232 Th, and 40 K. The A s values were ranged (4.3 ± 0.2-22.6 ± 0.2), (1.9 ± 0.1-4.2 ± 0.1), and (39.8 ± 0.2-86.0 ± 0.4) B q /k g , respectively. The mean calculated value of radium equivalent (Ra eq ) was 20.2±0.2 B q /k g . The annual effective dose rate of gamma (H ann ) was 0.13 mS v /y. Fortunately, the H ann value of the samples is lower than the world average value of 0.48 mS v /y.
