There have also been a number of reports of the presence of dissolved radon in groundwater from India. by Dr. Nitish Priyadarshi Presence of high levels of Radon (222 Rn) has been reported from groundwater in Bangalore city, Keolari-Nainpur area, Seoni-Mandla district in Madhya Pradesh, Bathinda , Gurdaspur, Garhwal, Himachal Pradesh and Siwalik Himalayas and underground waters of the Doon valley in India. To ascertain the ground reality and the nature of the hazards, if any, a study was conducted by the Central Ground Water Board, Bangalore in and around Bangalore city. The analytical results of all the groundwater samples collected from the gneissic and granitic rocks shows Radon concentration is above the permissible limit of 11.83 Bq/l and at places the concentration is as high as hundred times. The radon gas is occurring in the groundwater of the area ranging from 55.96 Bq/l to 1189.30 Bq/l plus or minus error values. There is no relation between the radon concentration and the de...

It is now a globally emerging discipline. by Dr. Nitish Priyadarshi Humans live in lands. Most of them live in intimate contact with the immediate geological environment, obtaining their food and water directly from it. The unique geochemistry of these tropical environments have a marked influence on their health, giving rise to diseases that affect millions of people. The origin of these diseases is geologic as exemplified by dental and skeletal fluorosis, iodine deficiency disorders, trace element imbalances to name a few. Medical Geology is an emerging scientific discipline that examines the impacts that geologic materials and processes have on human and ecosystem health. Medical Geology: · Identifies and characterizes natural and anthropogenic sources of harmful materials in the environment. · Predicts the movement and alteration of chemical, infectious, and other disease-causing agents over time and space. · Provides an understanding of how people are exp...
