Geo-Environmental
Studies relating to mining, urban, industrial, coastal and desert management
for sustainable development
Dr.
V. M. Choubey, Scientist ‘F’ Wadia Institute of Himalayan Geology, Dehradun has undertaken studies to characterize the
behavior of sub-surface radon migration in relation to various
geo-environmental conditions in the Himalayan region.
His
work on western part of the Lesser and Higher Himalayas has shown that the deep
seated fault planes facilitate easy escape of radon from the earth’s interior
to the surface. Comparative study of radon measurements by him in spring waters
before and after the Chamoli earthquake has shown that radon concentrations
enhanced substantially after the earthquake in the worst affected areas around Rudraprayag and Chamoli. Exceptionally high values are
present in few springs of the Bhilangana valley in
the proximity of mega Himalayan thrust system. Radon concentration studies
carried out by Dr. Choubey across landslide profiles are significance in
landslide hazard assessment and mitigation. Dr. Choubey has identified three
different clusters of high radon values in densely populated
In
recognition of his innovative research on radon emanations related to the
complex thrust tectonics in various parts of
