The background ionizing radiation of the environment was determined by measuring the radiation exposure rates using Radalert-200 and Geographical Positioning System (GPS). Radiological health parameters and effective dose to different organs of the body was estimated. The average exposure rate of 0.00017mSv/h (0.017mR/h) measured was relatively higher than the world acceptable value of 0.00013mSv/h (0.013mR/h ). All the radiological risk parameters estimated are relatively high. The result of this work shows that the mining µactivities have enhanced the radiation level of Ishiagu and health status of the populace.</p> C. Mgbeokwere, C. P. Ononugbo, A.

Structural characterization and presence of functional groups are carried out using powder X-ray diffractogram and FTIR spectroscopic studies respectively. Thermogravimetric analysis and differential thermal analysis are carried out to determine the melting property and it shows good thermal stability among organic crystal showing result at 166<sup>°</sup>C. Second Harmonic Generation efficiency study is carried out using Nd: YAG laser, this revealed that titled compound is good for NLO characterization and applicable in optoelectronics. PL wavelength present in visible region conclude that sample shows fluorescence property.</p> Arpitha Kumari, Ganesh Sanjeev, Boja Poojari, P. V.
