“…The data reported in this study is quite greater than 651 ± 22.85 Bq/m 3 and 250 ± 11.355 Bq/m 3 for Barkin Ladi and Jos South respectively as reported (Abdulwahab, Asuku et al 2020). The reason for variation in the reported radon concentration for these areas may be attributed to their geology (Vaupotic, Krizman et al 1994), climatic condition (Vaupotič, Kobal et al 1998), uranium grade and complex effects of host rock, uranium ore grade as well as uranium mineralogy (Fleischer 1983, Morawska andPhillips 1993).…”

Radon and its short-lived progenies contributed significantly to natural background radiation. Long-term exposure to such radiation increases the probability of lung cancer to persons. To assess the radiological hazards associated with the inhalation of radon gas from ore dust in Mazat and Kafi-Habu mining sites of Plateau, Nigeria, 12 soil samples from an abandoned tailing dump ground were collected and analysed for radon using RAD-7 electronic detector. The dose rate of each sampling point was directly measured using RADOS RDS -120 portable survey meter. The results gave a mean radon concentration ranging from 771.51 ± 21.9 Bq/m3 to 5666.13 ± 28.8 Bq/m3 with 3451.13 ± 42.9 Bq/m3as the average value for all measurements. The average concentration of measurements from Mazat and Kafi-Habu is 3671.6 ± 41.2 Bq/m3 and 3010.16 ± 46.5 Bq/m3 respectively. The average values obtained from the analysis are significantly higher than the upper limit of 300 Bq/m3 set by the International Commission on Radiological Protection (ICRP) suggesting quick remediation on the host communities. The geometrical mean value of Dose Rate (DR) and Annual Effective Dose Equivalent (AEDE) were 870 nGy/hr and 1.04 mSv/yr respectively. Again, these values are above the global average limits of 59 nGy/hr and 1 mSv/yr. The result indicates that miners working in those sites and dwellers of the study areas are at higher risk of getting exposed to radon and need to employ protective measures. This work is useful in monitoring and control of radon level for the on-site workers and the

“…The reason for this difference could be a function of the geological structure of the area, the depth of the water well and also differences in the climate between the months of March and June. Others have reported that the geological structure of an area is a predominant factor for high radon concentration [15] and climate condition is also an important factor [16].…”

Radon, a naturally occurring radioactive noble gas, is the main source of the natural radiation that is received by the population. It derives from the traces of radium in rocks and can diffuse directly or as solution in water to the earth's surface. Measurements of radium and radon concentration in a total of ten different well waters sampled at about 100 m depth in the Afyonkarahisar area of Turkey have been made. It was found that the concentration ranged from 0.42-28.82 Bq·L Ϫ1 for radon and from 0.07-7.16 Bq·L Ϫ1 for radium. A 99% correlation between radon and radium concentrations was found. From these data the average annual effective dose equivalent from radon and radium in the water have been estimated to about 73.8 and 778.96 Sv·y Ϫ1 , respectively.

“…However, the ventilation rates in the dwellings are influenced by the habits of the people residing in the dwellings. 9 Studies on environmental radiation levels in the dwellings constructed under Double Bedroom Housing Scheme at Erravalli and Narasannapet model villages of Telangana state were carried out with the financial support from the Telangana State Council of Science and Technology which functions under the aegis of the Department of Environment, Forests, Science and Technology, Government of Telangana state, India. The present paper deals with the environmental radiation levels in these dwellings, which should be helpful in suggesting safe human habitat from the radiological protection point of view.…”

Quantification of natural background gamma radiation levels in indoors has attracted mounting interest for the past few decades due to the detrimental effects of radiation. The indoor radiation levels depend on many parameters like geology, building materials, temperature, ventilation, etc. The natural background gamma radiation levels were estimated using a μR-Survey Meter in indoors and outdoors of dwellings constructed under the Double Bedroom Housing Scheme of Telangana state government at Erravalli and Narasannapet model villages. The average gamma radiation levels in the Erravalli village was found to be 2873 ± 413 μGyy−1, while in Narasannapet village it was 2621 ± 355 μGyy−1, which are relatively high as compared to the national average 775 ± 370 μGyy−1. The indoor to outdoor ratio of natural background radiation levels varied from 0.74 to 1.52 with an average of 1.08 which is in the global range. The variation of these levels with different types of dwellings has also been discussed.
