The application of beta rays in the medical field covers multiple aspects such as radiation therapy, medical imaging, and preparation of radioactive markers. With the continuous advancement of technology and the deepening of medical research, the application fields of beta rays will continue to expand and improve.

1. Radiation therapy

Tumor treatment: beta rays are widely used for tumor treatment because of their penetrability and destructive effect on biological tissues, especially for superficial tumors that are vulnerable to surgery and difficult to cure, such as skin cancer and breast cancer. By placing a radioactive source near the tumor, beta rays can directly act on cancer cells, disrupting their DNA structure and achieving therapeutic effects. This therapy effectively kills cancer cells and reduces the risk of recurrence while preserving normal tissue.
Skin disease treatment: Beta ray applicators are also important tools in nuclear medicine applications, used to treat skin diseases such as skin capillary hemangiomas, keloids, chronic eczema, and red wine stains. The principle is to use the radiation effect of beta rays to directly act on diseased tissues, inhibit their growth and reproduction, while protecting normal tissues from damage.

2. Medical imaging

Nuclear medicine imaging: Beta rays also have important applications in medical imaging. In nuclear medicine imaging, patients will ingest drugs containing radioactive markers, and the radioactive isotopes in these drugs will release beta rays. By detecting the radiation of these beta rays, doctors can obtain imaging information about the internal tissues and organs of the human body, which can help diagnose diseases.

3. Preparation of radioactive labeling agents

Drug tracking: Beta rays can also be used to prepare radioactive markers, which are used to track and observe the distribution of drugs in patients' bodies. By labeling radioactive isotopes into specific compounds, doctors can understand the metabolic pathways and effects of drugs in the body, thereby optimizing treatment plans.

4. Safety and Protection

Skin damage risk: Although beta rays have a wide range of applications in the medical field, they may also cause damage to the skin. Therefore, when using beta rays for treatment or diagnosis, it is necessary to strictly follow safety operating procedures to ensure the safety of patients and medical staff. At the same time, necessary protective measures should be taken for areas that may be exposed to beta radiation, such as wearing protective clothing, gloves, etc.

5. Typical application cases

Treatment of skin capillary hemangiomas: For lesions such as skin capillary hemangiomas, beta ray patch therapy is popular among patients due to its significant therapeutic effect, easy operation, and obvious cosmetic effect. By selecting the appropriate dosage and irradiation time, diseased tissue can be effectively removed without damaging normal skin.
