Solid State Nuclear Track Detector (CR-39) is used to describe the behavior of radiation shipped, radiation dose and determine a possible radioactive contamination. The environment that surrounds us contains small amounts of radioactive (unstable)elements or radionuclides (U, Th)that are derived from primordialand secondary cosmogenic sources. In addition to natural radio- active materials, technologically generated radioactive materials and man-made (artificially produced) radionuclides have been introduced into ecosystems due to the proliferation of different nuclear applications in industry, medicine, and research.
