Thyroid and lung counters


Product Overview

The HA4700 thyroid and lung counter is mainly composed of a thyroid detector, a lung detector, energy spectrum analysis software and dose assessment software, passive efficiency calibration software (optional), a computer, a complete set of shielded seats, etc. It can simultaneously measure the content of radioactive nuclides in the human thyroid and lungs, and evaluate the dose level of human body exposure based on the nuclide measurement results.

Features

① Adopting all-Chinese spectrum analysis and internal irradiation dose assessment software;

② Equipped with automatic spectrum stabilization, energy calibration, peak search, peak analysis, activity meter calculation, uncertainty analysis and other functions;

③ Gain and high voltage adjustment can be performed, real-time display of real time/live time, discrimination threshold and other functions can be displayed;

④ Built-in common radionuclide library, support users to add new nuclides independently;

⑤ Passive γ detection efficiency self-calibration can be achieved;

⑥ According to different options such as nuclides, metabolic time, age, tissues and organs, the influence of different factors on internal irradiation dose is fully considered, and the internal irradiation dose of each organ is estimated;

⑦ Automatically output measurement analysis report, support external printing;

⑧ Adopt chair-type measurement method, and the measurement height and angle are adjustable.
