In this field, various radiochemistry methods and procedures are studied, applied and developed in order to investigate environmental radioisotopes using alpha spectroscopy with two PIPS (Passivated Implanted Planar Silicon) detectors. Some researches of this field are: the study about features of analysis system, ranges of alpha particles, the study of creating uranium standard source, investigation of radioisotopes 226Ra in bottled water and 210Po as well as 210Pb in cigarettes.
