Gamma (γ) rays and beta (β) rays play important roles in nuclear technology applications, especially in the field of biological research irradiation. The following introduces the applications of these two types of radiation in biological research irradiation:

1、 Application of Gamma (γ) rays in biological research irradiation

Sterilization technology:

Medical device sterilization: Gamma irradiation technology is one of the most commonly used irradiation sterilization techniques, widely used for the sterilization of disposable medical devices. More than 40% of disposable medical devices use this technology for disinfection to ensure the safety of surgeries, wound care, and other medical treatments. Gamma irradiation can penetrate various materials, products, and packaging, making it particularly suitable for batch sterilization and processing of large packaging.



Safety and reliability: Gamma irradiation uses durable industrial equipment, with a relatively simple process controlled by a small number of easily determined and validated parameters. This makes the technology highly reliable and has a normal operating time, reducing the need for skilled experts.

Nuclear medicine applications:

Radionuclide imaging: Gamma ray spectroscopy technology is used in nuclear medicine for in vitro radionuclide imaging, such as bone scanning, thyroid imaging, kidney imaging, myocardial imaging, etc., to help doctors diagnose diseases.



Radioisotope therapy: Utilizing the radioactive killing effect of radioactive isotopes, gamma rays are also used in tumor therapy to target and deliver radioactive isotopes to tumor tissue, killing tumor cells.

Biological Science Research:

Radiation mutagenesis: Gamma rays have the ability to induce gene mutations and can be used for genetic modification and breeding in biological science research. Through radiation treatment, genetic variation can be induced in organisms, thereby screening out new varieties with excellent traits.

2、 Application of Beta Radiation in Biological Research Radiation

Biological experiments:

Radioactive tracer: Beta rays are often used in radioactive tracer experiments due to their strong penetration ability. By labeling specific biomolecules or cells, scientists can track their distribution, metabolism, and interaction processes within the organism.

Cytological research:

Research on cellular radiation damage: Beta rays can penetrate the cell wall and ionize the interior of the cell, thus being used to study the effects of radiation on cell growth, division, and genetic material. This research helps to understand the potential hazards and protective mechanisms of radiation on living organisms.


3、 Safety precautions

Radiation protection: Due to the radiation nature of both gamma rays and beta rays, strict adherence to radiation protection regulations is necessary during biological research irradiation to ensure the safety of laboratory personnel and the environment.

Dose control: Radiation dose is one of the key factors affecting experimental effectiveness and safety, and must be precisely controlled according to the experimental purpose and the tolerance of the organism.

In summary, gamma rays and beta rays have broad application value in the field of biological research irradiation, but it is also necessary to pay attention to their potential safety risks and take corresponding protective measures.
