Abstract: (6191 Views)
Several characteristic emission lines due to the metal target (Cu) were investigated in the presence of radon trace in the atmospheric air using Q-SW Nd:YAG laser induced plasma within the irradiation control chamber. Regarding the previous experiments the emission lines of metal species in (Rn+air) are noticeably enhanced respect to those in the synthetic air, while those peak intensities instantaneously decreases due to radon decay, such that the radon's half-life can be determined by an optical method too. Here we made an attempt to utilize optical methods in order to determine nuclear characteristics accordingly.
Keywords: Laser Induced Breakdown Spectroscopy, Radon, Characteristic Emission Spectra, Radon\'s Half-Life
