“…While, the annual effective dose of thoron ranged from the highest value of 3.28 mSv y -1 for sand and the lowest value of 0.12 mSv y -1 for gravel, with an average of 0.49 mSv y -1 as shown in Table 1. This study showed all the calculated effective annual doses generated from radon and thoron to building materials were in the range of limit recommended ICRP action levels (3-10) mSv y -1 [20,21]. 2).…”

Radon, Thoron and their short-lived daughters have a high contribution to background radiation, as long-term exposure causes the risk of lung cancer. In current study, five types of building materials with a total 55 samples in Al-Shatra City, Dhi-Qar Governorate, Iraq collected to measure the radon and thoron concentration by using CR-39 solid state nuclear track detector. The results showed that the average radon concentrations in all samples were (103.53±55.94) Bqm−3, while the average thoron concentration was (53.20±44.69) Bqm−3. On the other hand, the annual effective dose of radon ranged between (0.85-6.46) msvy−1, with an average of 2.61msvy−1. While, for thoron concentration was ranged between (0.12-3.28) msvy−1, with an average of 1.49 msvy−1. The annual effective dose was found acceptable limit (3-10 msvy−1) recommended by the International Commission on Radiological Protection (ICRP). On the other side, the average Polonium concentrations (218Po, 214Po) have been found to be 2.053 KBqm−3, 0.866 KBqm−3, respectively.

“…After 60 days, CR-39 detectors were etched chemically by 6.25 N from NaOH solution that dilute with 250 ml of distilled water at 70 o C for 6 hours. Then, the tracks were recorded using Olympus optical microscope with a magnification of 400X [15,16]. The track of α-particles densities are calculated using equation [17][18][19]:…”

Long-term exposure to radon increases the risk of developing lung cancer. There is a considerable public concern about radon exhalation from building materials and its contribution to indoor radon levels. To address this concern, radon exhalation rates were determined for 24 different samples of building material commonly used in Al -Diwaniyah, Iraq dwellings, using solid-state nuclear track detectors (CR-39). The highest contribution is found in Granite from Italy, 169.04 ± 11.38 (Bq/m 3 ), 386.184 (mBq/m 2 h), and 4.26 (mSv/y) for radon concentration, surface radon exhalation rate, and the annual effective dose, respectively. On the other hand, the lowest contribution is found in Gypsum from Najaf -Iraq with radon concentration (Bq/m 3 ), radon exhalation rate (mBq/m 2 h), and the annual effective dose (mSv/y) of about 11.40 ± 0.11, 22.716, and 0.284. The obtained average values of these three quantities are 104.276 ± 7,50, 108.21, and 1.45, respectively. The average annual effective dose of radon concentrations is acceptable, compared with the standard limit value presented in ICRP.

“…The solid state nuclear track detecion (SSNTD),they are widely used plastic materials and have great popularity in the field of detecting heavy charged particles such as alpha particles and proton particles because they are inexpensive, easy to use, available, durable and effective [1][2][3]. It is a simple technology that does not require large or complex electronic devices in its use that form paths such as polymers whose sensitivity is very high to the particles [4,5].…”

This paper describes the synthesis and development of new polymers for solid state nuclear trak detector of two novel poly Allyl cloride – co Acrylic acid and diethanol amine of polymeric detectors of alpha charged particle tracks. The detectors were irradiated by two radioactive sources, Amercium (Am-240) and Polonium (Po-210) for 5 hours, and traces of alpha particles were seen in the microscope and their diameters were measured. The results showed the density of tracks of alpha particles from (Am-240) and (Po-210) are 295.86, 655.33 respectively, while the average of their diameters are 5.83, 4.78 respectively.
