HA4700-M thyroid counter
Product Overview
The HA4700-M thyroid counter is primarily composed of a sodium iodide detector, energy spectrum analysis software, passive efficiency calibration software (optional), a computer, and a removable, adjustable stand. It uses energy spectrum analysis technology to measure the level of radioactive nuclides in the human thyroid gland and assesses the dose level in the human body based on the International Commission on Atomic Radiation (ICRP) standard metrological conversion method. It can also be used for lung radiation detection in emergency situations.

It can also be used for lung radiation detection in emergency situations.
Applications
This product is used in nuclear medicine to measure I-131 activity and dose assessment in the patient's thyroid gland. It can also be used for on-site measurement of radionuclide activity in human organs during nuclear emergencies, at nuclear power plants, at reprocessing plants, and at special nuclear material processing sites, serving as an emergency response device for disease prevention and control centers.
Features
① Equipped with a movable, height- and angle-adjustable stand, it facilitates measurement positioning.
② The system offers a simple workflow and a fully Chinese interface for rapid thyroid and lung activity measurements.
③ Features include automatic spectrum stabilization, energy scaling, peak detection, repeated peak analysis, activity calculation, and uncertainty analysis.
④ Gain and high voltage adjustments are available, along with real-time display of live/live time and discrimination thresholds.
⑤ A built-in library of commonly used radionuclides allows users to add new nuclides.
⑥ Directly input diagnostic conclusions, automatically output measurement and analysis reports, and support external printing.
