Thallium activated sodium iodide (NaI(Tl)) detector and multi channel analyzer has been utilized to measure gamma rays emitted by radio nuclides found in soil samples of south-west (SW) region of Punjab state, India where elevated level of uranium of around value of 700µg/l in groundwater has been reported. For comparative study, soil samples were also collected and analyzed from west (W) and north east (NE) regions of the state. Uranium and potassium has been found to be comparatively higher in SW region whereas thorium level is higher in W and NE part of Punjab state. Overall concentration level of naturally occurring radio nuclides (40)K, (238)U and (232)Th has been found to be varied from 260.1±17.3 to 728.2±27.7, BDL to 41.9±10.3 and 29.5±7.1 to 88.1±6.2Bq/Kg respectively. Overall average level of (40)K and (232)Th has been found to be higher as compared to world's average concentration level. Average radium equivalent activity (134.8±23.03 (σ) Bq/Kg), dose rate (61.9±10.3nGy/h), outdoor and indoor dose (0.30±0.05 and 0.08±0.01 mSv/year), external and internal hazard index (0.36±0.06 and 0.42±0.08) has been calculated.

Pollutants, present in soil, which exhibit radioactivity.
Methods used for studying the interactions of antibodies with specific regions of protein antigens. Important applications of epitope mapping are found within the area of immunochemistry.
Radiation from sources other than the source of interest. It is due to cosmic rays and natural radioactivity in the environment.
Double-stranded nucleic acid molecules (DNA-DNA or DNA-RNA) which contain regions of nucleotide mismatches (non-complementary). In vivo, these heteroduplexes can result from mutation or genetic recombination; in vitro, they are formed by nucleic acid hybridization. Electron microscopic analysis of the resulting heteroduplexes facilitates the mapping of regions of base sequence homology of nucleic acids.
A species of gram-negative, aerobic bacteria that causes MELIOIDOSIS. It has been isolated from soil and water in tropical regions, particularly Southeast Asia.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
