Product Overview
VEGASOURCE 31 is used to contain and shield radioactive isotopes, emitting gamma rays through a controllable beam channel toward the vessel being measured. Its design balances radiation safety and measurement stability, making it suitable for extreme working conditions in industries such as chemicals, petrochemicals, power, and metallurgy.
Main Structural Components
- Shielding housing: Made of high-density lead or tungsten alloy to reduce external radiation dose.
- Source assembly: Contains isotopes such as cesium-137 or cobalt-60, selected according to activity level.
- Beam channel: A switchable collimating aperture that controls the direction and angle of the emitted radiation.
- Operating mechanism: Manual or pneumatic switch to turn the source on/off.
- Mounting bracket: Compatible with various on-site installation methods to ensure collimation alignment.
Working Principle
When gamma rays emitted by the radioactive source pass through the measured medium, some rays are absorbed or scattered, and the intensity attenuates with changes in medium thickness or density. The detector receives the remaining rays and converts them into electrical signals, which are processed by the transmitter to output level or density values.
VEGASOURCE 31 uses a collimated beam to concentrate the rays toward the detector, improving the signal-to-noise ratio and reducing scattering interference, thereby ensuring measurement accuracy.

Installation and Commissioning Steps
Correct installation is a prerequisite for ensuring measurement accuracy and radiation safety. The following steps are recommended.
- Confirm the on-site installation position to ensure collimation alignment between the source container and detector.
- Secure the mounting bracket and check that bolt torque meets the manual requirements.
- Connect the pneumatic or manual operating mechanism and test whether the switching action is smooth.
- Complete electrical wiring and detector commissioning with the source in the closed state.
- Gradually open the beam according to procedures, observe the signal, and calibrate the measurement range.
- Record the initial dose rate and confirm compliance with local radiation protection standards.
Safety Precautions
- A radiation safety license must be obtained before operation, and it must be performed by certified personnel.
- Disassembly or maintenance work is strictly prohibited while the source is open.
- Regularly use a radiation dosimeter to check the dose rate around the container.
- Transportation and storage must comply with national regulations for the transport of radioactive materials.
- Disused sources must be recycled by qualified units and must not be disposed of arbitrarily.
Selection and Procurement Recommendations
When purchasing VEGASOURCE 31, the isotope type and activity should be determined based on the measured medium, vessel wall thickness, measurement range, and on-site safety requirements. It is recommended to also request the Chinese manual, radiation safety data sheet, and compliance certificates for subsequent acceptance and filing.
