“…This theory was found to relate to the data gathered about diggers in Colorado and Mexico City [12]. A few examinations have additionally demonstrated that a few tumors, for example, leukemia, kidney growth and protozoa can be credited to presentation to radon [13], [14]. The present work will help in understanding the status of outdoor radon, thoron and their progeny concentrations and status of the exhalation of these gases from air.…”

The levels of radon, thoron and their progeny concentrations in Al-Nayriya, Al-Musbah Street, Nawab Al-dhubat and Al-mashtel, as well as Canal Street in southeast Baghdad were studied by using The Twin Cup Dosimeter. A total of 15 samples selected from 5 regions (3 samples from each region) in Baghdad city have been placed in the dosimeters for 100 day. The average radon and thoron concentrations were found to be 45.47 and 43.15 Bq/m3 respectively. Their average progeny concentrations were found to be 4.91 and 1.16 mWL. The dose received by persons living in the studied areas is less than the internationally permissible limits, which were determined by the ICRP of 3-10 mSv /y.

“…2–4 In India, many researchers are engaged in the measurement of indoor radon levels in dwellings for health risk assessments and its control. 5–10 The residential radon is regulated by an action level of radon concentration between 200 and 300 Bq m −3 based on International Commission on Radiological Protection (ICRP) recommendations. 11…”

Radon (222Rn), the immediate decay product of radium, is a causative agent of lung cancer. The seasonal indoor radon concentration in houses with different floorings, walls and roofs has been measured in Northern Rajasthan, India. The measurements were made in 100 houses using LR-115-type II plastic track detectors over four successive three-month periods (winter, spring, summer and autumn). The mean values of indoor radon concentrations in winter, spring, summer and autumn were determined to be: 176 Bq m−3, 131 Bq m−3, 120 Bq m−3 and 151 Bq m−3, respectively. The annual average indoor radon concentrations in the dwellings were found to vary from 117 to 215 Bq m−3 with an average of 144 Bq m−3. In ∼10% of the dwellings the indoor radon activity concentration values lies in the range of action level (200–300 Bq m−3) recommended by International Commission on Radiological Protection. The annual effective dose received by the residents of the study area varied from 2.0 to 3.67 mSv with an average of 2.46 mSv. The seasonal variation in indoor radon reveals the maximum value in winter and minimum in summer. The influences of the factors linked to building characteristics in relation to radon measurements were examined.

“…The results indicated that selecting these traits is useful to improve the dry stigma yield of saffron ( Figure 3 ). Genetic associations are more significant in correlation studies than phenotypic correlations due to removing environmental effects in calculating genetic correlation coefficients ( Singh et al, 2005 ). Our study indicates that saffron yield attributes and the yield itself correlate greatly with altitude.…”

Agro-Climatic Suitability Evaluation for Saffron Production in Areas of Western Himalaya

Saffron (Crocus sativus L.) is an expensive spice crop cultivated successfully in Iran, Afghanistan, India, Greece, Morocco, Spain, and Italy. The present study was conducted during the periods 2018–2019 and 2019–2020 to evaluate the morphological, yield and quality parameters of saffron in six different regions of non-traditional areas of the western Himalayas. The two experimental factors were “year” and “location.” The experiment was conducted using a factorial randomized block design with three replications. Yield attributes, viz., number of flowers, fresh flower yield, fresh stigma yield and dry stigma yield were significantly higher in location L3 compared to other geographical locations. Dry stigma yield in location L3 was higher by 50.0, 41.2, 33.3, 14.3, and 9.1% compared to locations L6, L5, L1, L4, and L2, respectively. These were characterized by the appropriate climatic conditions, viz., high altitude, sandy-loam texture of the soil, optimum temperature, lesser relative humidity and total rainfall, demonstrating that it is possible to cultivate this spice even in non-traditional areas of the western Himalaya. Positive correlations were established for stigma yield with increased altitude and lesser rainfall. Secondary metabolites viz., crocin and picrocrocin increased significantly with the increase in altitude; however, a reverse trend was recorded for safranal content. Total phenolics and flavonoids were significantly higher in the geographical location of Kinnaur, H.P. (L1) and Bharmour, H.P. (L4). In conclusion, the assessment of different geographical locations and soil types is particularly necessary to encourage saffron production and its qualitative traits. Based on current findings, saffron can be grown successfully in some non-traditional locations of the western Himalayan regions.
