Product Introduction

An activity meter is an instrument used to measure the particle activity of samples. Particle activity refers to the quantity and mass of exposed chemical groups on particle surfaces, as these groups determine the capacity of particles to react with other substances.
The activity meter monitors and records the activity, motion and variation of substances or systems in real time, and quantitatively measures and analyzes the magnitude of activity, motion and variation of substances or systems.

Product Performance

Capable of measuring common radionuclides for nuclear medicine, including 99mTc, 131I, 67Ga, 201Tl, etc.
Supports therapeutic radionuclides for internal radiotherapy such as 153Sm, 90Y, 186Re, as well as positron-emitting radionuclides including 18F, 15O, 13N.
One-key automatic background radiation subtraction; no manual zero adjustment required.
Automatic measurement and range switching upon sample placement, delivering fast and precise readings.
Radionuclide calibration factors can be modified and saved via keyboard without dedicated development tools.

Application Fields

Department of Radiology：The Department of Radiology is a comprehensive department integrating imaging diagnosis and interventional therapy. Radiological diagnosis employs X-rays, gamma rays and other radiation to penetrate the human body, rendering images of internal bodily structures and organs on fluorescent screens or radiographic films, enabling evaluation of human anatomical morphology, physiological functions and pathological lesions.

Department of Radiation Oncology：Radiation oncology is a localized therapeutic modality that uses ionizing radiation for cancer treatment. Radiation sources include alpha, beta and gamma rays emitted from radioactive isotopes, as well as X-rays, electron beams, proton beams and other particle beams generated by various X-ray therapy units and medical accelerators.

Department of Nuclear Medicine：It adopts nuclear science technologies for disease diagnosis and treatment. As an integrated department combining imaging, therapeutic services, scientific research and teaching, it serves as one of the core modalities in modern medicine.
