Developed a method in 1988 for interpretation of radon data for purposes of recognition of buried uranium ore deposit based on the intercept parameter of linear regression model that caught attention of News Media, The Times of India; published a citation under the headline 'New Method to find Uranium'. After 20 years, in 2008, other workers [Ramola et al., Radiation Measurements 43 (2008) 98 - 101] echoed the same conclusion.
Processed and interpreted airborne radiometric data in 1989 by statistical significance analysis for demarcating an area of high uranium potential lying within longtitude range 79 deg 00 min to 79 deg 15 min and latitude range 16 deg 30 min to 16 deg 45 min which proved three years later to be exactly Lambapur uranium deposit.
Developed a method in 1990 for statistical evaluation of optimum radon emanometric technique based on an idea of poor correlation between radon and soil radium for which he received paper reprint requests from univ. of Gottingen, Germany; Bhabha Atomic Research Centre, India; Institute of Natural Resources, Spain; Lawrence Berkley Lab., California, USA, Indoor Environment Prog., and Physical Research lab., India.
An work based on multivariate R-mode factor analysis for finding geochemical association of radioactive and trace elements in the quartz pebble conglomerate of Dhanjori basin, Singhbhum, Jharkhand State, India in 2000; was included in a title named 'High Resolution Provenance' made by Prof. Darrel Henry of Lousiana State Univ., USA.
An work on new high background radiation area in the geothermal region of Eastern Ghats Mobile Belt (EGMB) of Orissa, India in 2006; was in the selection of 'Science Direct Top 25 Hottest Articles July - September 2006'.

An work on spatial distribution of uranium-series-disequilibrium in black shale of Mussoorie syncline and its implications in exploitation of secondary uranium resource in 2009; was put in 'Top Ranked' by WorldWideScience.org maintained by the U.S Dept. of Energy.
