Description

Technical Field

[0001] The utility model relates to the technical field of isotope releasers, in particular to a dual-source solid isotope releaser. Background Art

[0002] Isotope sources refer to natural and artificial radioactive nuclide sources. According to the type of radiation released, there are three types of radioactive nuclide sources: α, β, and γ. γ radiation sources are the most widely used radioactive nuclide sources, which are used in gas, liquid and solid radiation chemistry research and radiation processing technology. The α and β radiation sources release α particles and β particles with low penetrating ability, which are suitable for irradiating gaseous substances and serving as internal radiation sources. Isotope source releasers are devices that can release isotope radiation, which are usually used in the fields of radioactive tracing, radioactive timing and radioactive thermometry.

[0003] The isotopes inside the solid isotope releaser are usually immovable. The isotopes are usually fixed inside the releaser and release radiation through the decay process. The internal isotopes are gradually consumed during the release process until they are exhausted. Since the isotope source is fixed inside the releaser, the user cannot flexibly adjust the position of the source or change the distribution of the source according to the needs, which limits the scope of use in certain application scenarios. The isotope source is fixed inside the solid isotope releaser and is disposable. Once the isotope is exhausted or the life of the releaser ends, the entire releaser needs to be discarded and cannot be reused. This increases the cost of use and wastes resources. Therefore, it is necessary to propose a dual-source solid isotope releaser. Utility Model Content
