چکیده
Abstract Compared with other methods for measuring radioactivity in water, liquid scintillation measurement has the outstanding advantages of fast sample pretreatment, simple method and high detection efficiency. Based on spectrometer (SIM-MAX LSA3000B), 14 C 90 Sr- Y are selected as typical nuclides to study change TDCR quenching correction curve under different activity concentrations, basic radioactive water samples concentrations is proposed, which applied lake mountain spring tap mineral rainwater. The results show that total time this less than 60 minutes, error 20%, obviously superior existing nuclear emergency conditions.

The production rate is 7.5 kg isotope C-14 yearly. The C-14 concentration stays approximately constant due to rapid mixing of the atmosphere, although the cosmic intensity is higher at the poles due to the deflection of charged cosmic particles along the magnetic field lines of the earth (corresponding to neutron intensities in the ratio 5:1 at the poles and the equator, respectively). Conseque...

Measurement of Strontium-90 in the Persian Gulf Fish by Extraction Chromatography with Sr-resin and Liquid Scintillation Counter
Background: Despite its beneficial effects on human life, the nuclear industry has its own risks. Strontium 90 (90Sr) is one of the most dangerous radionuclides produced by the uranium 235 fission, and replaces the bone calcium in the human body, which causes cancer. Ensuring the safety of nuclear facilities to protect employees, people and the environment is among the main goals of nuclear saf...
