“…Hence, each average of 222 Rn reading for raw materials were deducted to the background reading (0.977 pCi/L) to obtain the nett 222 Rn concentrations by using the formula in Eq. 1 [2,8]. Thus, nett of 222 Rn concentration from raw red brick was revealed at -0.22 pCi/L.…”

The study revealed the synergism effects of concrete plaster and coatings in reducing 222 Rn from a marketable red brick. The methodology applied is the common practice in construction industry for wall finishing. 222 Rn concetrations level from red brick coated with three different type of coatings were measured within 5 consecutive days within 30 min times interval. The nett 222 Rn concentration of raw red brick (uncoated) was-0.22 pCi/L. From the results, 222 Rn concentration has drastically decreased after coated with coating B and C. 222 Rn cocentration seems to decreased with the range of-0.9 pCi/L to-0.3 pCi/L after coated with coating B and-0.8 pCi/L to-0.7 pCi/L after coated with coating C. Coating B shown the best performance in reducing 222 Rn emanations with lowest 222 Rn range concentration, high adhesion strength and good dynamic viscosity properties.

“…The maximum average value of radon concentration was observed 14.7 Bq/l in well water used for drinking and irrigation while minimum was found 5.37 Bq/l in tap water used for drinking. Saidi et al (2016) studied the radon concentration in three light foamed concrete which were produced by using different cement to aggregate ratios to find the factor that influence the production of radon from fabricated building materials (Saidi et al, 2016). The results revealed that LFC 3 has produced lowest radon concentration in air, followed by LFC 2 and LFC 1, respectively.…”

It is known that the inhalation and ingestion of radon gas could lead to the primary health risks for lung and stomach cancers. Besides the health hazards of radon gas, it has different geological applications. In this context, numerous studies have been reported all over the world. Different research groups in Malaysia have also conducted and reported numerous studies since several decades. However, these studies are scattered and need to be compiled for future studies in Malaysia. The main emphasis is to overview and compiles these articles that will work as baseline data for the level of radon gas in Malaysia.

“…Radon (222Rn) is one of the radioactive gases that contributes towards background radiations [1][2]. It is occurred naturally in the environment from the Uranium-238 decay series in the soil that originate from the Earth's crust.…”

“…Emanation of radon towards surrounding poses high risk for health due to the successively decay of their daughters of alpha (α) particles [1]. The inhalation of the gas and its decay products into the respiratory system will be absorbed by the lung tissues and unfortunately increases the risk of lung cancer and other health problems [2,[4][5][6][7].Theoretically, the 222 Rn concentrations might be influenced by its location, based on the activity that has been conducted such as mining industry and radiations work. Human-made of radioactive chemicals have enter the environment from activities such as mining and the use of radioactive materials in nuclear medicine, military, industrial applications, consumer products and nuclear power generation.…”

This study was determined the influence of radiation and non-radiation work activities over 222 Rn concentration levels in soil at selected areas in Universiti Sains Malaysia Health Campus. Radon Sentinel 1030 monitor was used to determine 222 Rn concentrations emanated from soil collected at Radiology Department and Nuclear Medicine Department (red areas), hospital lobby, hostel and Registry Department (public areas) and isolated area. Each reading was recorded within 30 min time intervals in a close perspex room for 5 cocecutive days to obtaine average 222 Rn concentrations reading. The results show the Radiology Department and hostel have obtained least amount of 222 Rn concentrations, which were 0.287 pCi/L and 0.246 pCi/L. Concentration of 222 Rn at Nuclear Medicine Department was 0.304 pCi/L, whereas 0.289 pCi/L in isolated area. Insignificant reading at Radiology and Nuclear Departments prove the proper application of radiation protection principle has been applied such as half value layer rule for wall thickness. Meanwhile, Registry Department and hospital building (public area) showed the highest concentration of 222 Rn which were 0.561 pCi/L and 0.462 pCi/L due to the natural environmental radiations that are mainly depending on geographical conditions, as the random properties of 222 Rn emanations cannot be controlled.
