“…All samples were crushed (separately) to a fine powder and sieved through a 0.5mm mesh. Each sample was oven-dried at 110°C for 3hours to reduce the moisture content [13]. Weighed samples of 200g were placed in polyethylene cylindrical beakers, of about 300ml each.…”

Twenty (20) different local and imported tiles were sampled from major hardware's in Bungoma. The samples collected were separately ground, sieved, through a 0.5mm mesh, dried at 110° C, weight and packed in a 200ml stoppered plastic bottles. The samples were stamped with identification numbers and kept for 30 days for secular equilibrium to be reached between the activity of 238 U, 232 Th , 40 K radium and their progeny. The average activity concentration of 238 U, 232 Th and 40 K was found to be 109±5.48Bqkg -1 , 11±0.55 Bqkg -1 and 1574±78.7 Bqkg -1 respectively. The average absorbed dose rate was found to be 140±7.03 nGyh -1 which is higher than the worlds average value of 60 nGyh -1 . The average radium equivalent was found to be 288±14.44 Bqkg -1 which is lower than the world limit value of 370Bqkg -1 . External and internal hazard indices were found to be 0.70±0.03 msvy -1 and 0.80±0.04 msvy -1 respectively. Therefore, the sampled tiles used in Bungoma county for construction has minimal radiological threat to population.

“…Among the reported active techniques, an accumulation chamber equipped with a scintillation cell monitor (Lucas cell Model 300 A + Radiation monitor Model AB-5, Pylon Electrics, Inc., Ottawa, Canada) (Hassan et al, 2009;Hassan, 2014;Hosoda et al, 2009), Alpha Guard (Saphymo, Germany), a solid state silicon detector (RAD7, Durridge Co. Inc., Bedford, MA, USA) or Radon Scout equipment (Sarad, Germany) were used to measure the indoor as well as the outdoor radon concentrations (Hassan et al, 2009;Catalano et al, 2015;Abdalla et al, 2019;Rafique et al, 2012;Matiullah et al, 2012). However, solid state nuclear track detectors (SSNTDs) such as CR-39, LR-115 or Makrofol can be inserted into a CAN-technique or Raduet (RadoSys Ltd., Budapest, Hungary), to measure indoor and outdoor ( 27 ) radon concentrations, as passive techniques (Hassan et al, 2009;Catalano et al, 2015;Abdalla et al, 2019;Rafique et al, 2012;Matiullah et al, 2012). The track detector method is extremely is simple and does not require any high budget equipment unlike other technologies, while its accuracy is comparable to other methods, which gives it an advantage.…”

Radon concentration at Tanis, Sharqai, Egypt, was measured at the site as well as at the laboratory using a sealed CAN-technique equipped CR-39 detector which was calibrated in advance. In situ measured radon concentration ranged from 72 ± 9 Bq m -3 to 144 ± 16 Bq m -3, while the equilibrium radon concentration of 20 soil samples collected from the same sites were ranged from 88 ± 12 Bq m -3 to 226 ± 36 Bq m -3 at the laboratory. The average radon concentration is less than the recommended value by ICRP of 300 Bq m -3 but it is higher than the recommended value by WHO of 100 Bq m -3 . The radon exhalation rate was ranged from (24 ± 3 to 61 ± 10 10 -4 ) Bq m -2 s -1 . It shows a good correlation with the radium content of a linear correlation factor of R = 0.97, which implies, the radium content is a useful index for radon parameters. Moreover, the radiation dose was calculated using radon concentration at sites and its value was ranged from 0.40 ± 0.05 to 0.79 ± 0.09 mSv y -1 for workers and from 0.054 ± 0.007 to 0.108 ± 0.012 mSv y -1 for visitors. From the obtained results, we assure there is no radiation health hazard from visiting the studied archaeological site.

“…Radium mainly enters the body through the food chain Radium, being chemically similar to calcium, tends to follow it in metabolic processes and becomes concentrated in bones. The alpha particles given off by radium and radon bombard the bone marrow and destroy tissues that produce red blood cells [13][14][15]. It may cause bone cancer.…”

Radon has been recognized as one of the major contributor to the natural radiation and health hazards in the human dwellings, working places and mining areas. Even lung cancer is expected if it is present in enhanced levels beyond maximum permissible limit. We have studied radium contents and radon exhalation (both mass and surface) rates in Menge mining and nonmining areas of the Benishangul Gumuz region in Western Ethiopia using the sealed Can technique and LR-115 type II plastic nuclear track detectors. Fifteen soil samples were collected over the study area according to the fraction of the populations and mining and non-mining areas. It is found that the values of radium contents vary from 1.20 to 3.94 Bq.kg-1 with an average value 2.44 Bq.kg-1. It is also found that gold mining areas have had relatively higher radium contents as compared to the other samples which are collected from non-mining areas. And radon exhalation study is important for understanding the relative contribution of the material to the total radon concentration found inside the study area. The radon mass and surface exhalation rates for the studied samples had the mean values of 2.16×10-6 Bq.kg-1 .d-1 and 1.14×10-4 Bq.m-2 .d-1 respectively.
