Radon exhalation from Libyan soil samples measured with the SSNTD technique

Estimation of Radon Concentration in Soil Samples from Cameron Highlands, Malaysia

“…Table 2, shows the comparison between radon concentrations in the present study with those elsewhere. The concentrations of radon in this area of study are remarkably lower than those for Pakistan, India, Egypt and Libya; whereas the values of radon are higher than those reported for Brazil , Binns et al, 1998, AbdElzaher, 2012, Mahur et al, 2013, Saad et al, 2013. Based on the comparison, it has been observed that there is also a variation in the values of radon levels among countries.…”

“…Besides affecting the public, it is responsible for many cancer deaths among uranium miners [UNSCEAR, 2000, Adams, 1991. In this concern, studies on soil have been carried out in different parts of the world, and much data is available in the literature Saad et al, 2013; Al-Nafiey et al, 2014). The Kinta district has many tin mining sites and is expected to have high background radiation from minerals, such as monazite and zircon.…”

Indoor radon variations in central Iran and its geostatistical map

“…The radon maps in many European countries and North America has been obtained and published (Wilkening, 1986;Crameri et al, 1989;Andam, 1992;Miles, 1998), such studies have started to pick up during past two decades in parts of Asia (Narayana et al, 1998;Mui and Wong, 2004;Singh et al, 2005;Badhan et al, 2010;Rafique et al, 2010), Latin America (Canoba et al, 2001;Magalhães et al, 2003;Espinosa and Gammage, 2003;Hadler et al, 2008) and Africa (Abo-Elmagd et al, 2007;Lindsay et al, 2008;El-Zaher, 2011;Saad et al, 2013).…”

Alpha Particles Concentrations from Soil Samples of Al-Najaf/ Iraq

“…The soil radon concentration contributing to indoor radon activity can be calculated according to the radon exhalation rate of soil samples according to equation (8) Where: φ is the air exchange rate that is equal 0.5 (hour) -1 , Sr is the internal surface area and Vr is the volume of the room. In present study, the ratio (S r ) to (V r ) is equal 2 m -1 (Saad et al 2013). Using the soil radon concentration contributing to an indoor radon activity factor, many radiation hazards indices due to radon such as effective dose equivalent (E P ) in the MLM·y -1 unit, annual effective dose (H E ) in the mSv·y -1 unit, the dissolved in soft tissues (D Soft tissue ) in the nGy·h -1 unit and dose rate due to alpha-radiation in the lung (D Lung ) in the nGy·h -1 unit, can be estimated as follows: The annual WLM (effective dose equivalent) can be calculated using equation (8), which was proposed by Nazaroff and Nero Jr.…”
