“…23 In parts of some countries, notably Italy and Sweden, communities using high radium content building materials such as volcanic tuff or alume shale for construction of houses; the radon exhaling from these building materials is a significant contributor to their indoor radon level. 24,25 Our results are in agreement with similar findings that mud contributes to a higher indoor concentration of radon than the cement based material. 20 Comparing the radon concentration obtained in our study (that is higher with comparison) with other results obtained, it was recorded that red brick and ceramic materials constitute low concentration values.…”

Measurements of radon concentration, surface and mass exhalation rates were made for 12 types (264 measurements) of building material samples frequently used in Sudan. In this survey, we used the can technique, containing CR-39, to estimate the radon exposure from building materials. The results of radon concentrations in the selected building materials ranged from 506 ± 79 Bq.m−3 in mud bricks of Aroma area to 128 ± 39 Bq.m−3 in ceramic material. The surface and mass exhalation rates ranged from 949 ± 70 mBq.m−2.h−1, 11.25 ± 1.76 mBq.kg−1 h−1 to 240 ± 35 mBq.m−2 h−1, 2.84 ± 0.87 mBq.kg−1.h−1, respectively. The effective dose was calculated that ranged from 3.59 ± 1.10 mSv.y−1 to 14.21 ± 2.23 mSv.y−1, for ceramic and mud materials, respectively. These results agreed with similar findings that mud contributes in a higher indoor concentration than the other investigated materials, mud was found to constitute an effective dose above the action level as quoted by the International Commission on Radiological Protection (ICRP).

“…On the contrary, raw materials containing phosphorus show low activity concentrations of 40 K (equal to a few dozen Bq kg ÿ1 ) but significant activity concentrations of radionuclides belonging to 238 U chain. In phosphate ores, activity concentrations of 238 U, 226 Ra and 210 Pb are equal to about a thousand Bq kg ÿ1 that is to say that they exceed the world average noticed in soils (UNSCEAR, 2000) and the natural background typical of the soils present in the study area (Sciocchetti et al, 1985) by two orders of magnitude. Uranium-238 activity concentrations noticed in phosphate ores taken into account in this survey (corresponding to about 100 ppm) fall within the range of values observed by several …”

“…The predicted concentrations of 238 U-series radionuclides are about 2e4 times lower than the local ground-level air concentrations (1.25 mBq m ÿ3 for 238 U-series radionuclides). Local background has been estimated in the manner suggested by UNSCEAR (1988UNSCEAR ( , 1993UNSCEAR ( , 2000 assuming a dust loading of about 50 mg m ÿ3 and taking uranium-series radionuclide concentrations in local soil of 25 Bq kg ÿ1 (Sciocchetti et al, 1985).…”

“…15 Radiation emission maps of the province have been drawn based on such geological features as type of rock, tectonic features, geothermic gradients, uranium deposits, and the presence of thermal waters. 16 TuV (tufo) from the volcanic area, which has a high emission of radon and thoron, 17 has been widely used as the main building material in the province.…”

Objectives-To investigate whether indoor radon or radiation might play a part in myeloid leukaemia as suggested by studies based on crude geographical or geological data for exposure assessment. Methods-For six months radon and radiation was measured with solid state nuclear track detectors and thermoluminescent dosimeters in dwellings of 44 adult male cases of acute myeloid leukaemia and 211 controls (all subjects deceased). Conditional logistic regression ORs (ORs) and 95% confidence intervals (95% CIs) were estimated for quartiles of radon and radiation and for municipality and dwelling characteristics. Results-The risk of leukaemia was associated with an increasing urbanisation index (p value for trend=0.008). An increased OR was found among those living in more modern houses (OR 3.0, 95% CI 1.4 to 6.6). Confirming the findings of a previous study in the same area, geological features bore a positive association with myeloid leukemia, even by adjusting for level of urbanisation. Contrary to expectations from the previous study, however, no association appeared between myeloid leukaemia and radon and radiation; for the highest quartiles of exposure, ORs were 0.56 (95% CI 0.2 to 1.4) and 0.52 (95% CI 0.2 to 1.4), respectively. Considering only subjects who had lived >20 years in the monitored home and adjusting for urbanisation, there was still no eVect of exposure to radiation. Conclusions-In view of the limited numbers, the results do not in general refute a possible risk of myeloid leukaemia from exposure to indoor radon or radiation, but decrease the credibility of such a relation in the area studied and also of other studies suggesting an eVect without monitoring indoor radiation. Some other fairly strong determinants have appeared-that is, level of urbanisation and living in modern houses-that might need further consideration. (Occup Environ Med 1998;55:106-110)
