brachytherapy
The term for implanting radioactive materials into tissues for treatment is called brachytherapy.

Brachytheraphy
In brachytherapy, radioactive materials are implanted directly into or near the tumor site to deliver a targeted dose of radiation to the cancer cells while minimizing exposure to surrounding healthy tissues. This technique allows for precise localization of the radiation dose, reducing side effects and improving treatment outcomes.
The most general term is "radiotherapy", or "radiation therapy", but that term would also include external sources of radiation being used to irradiate the target tissue. When radioactive sources are implanted to deliver a therapeutic dose of radiation, the term "brachytherapy" is used.
All radioactive materials can enter your body one way or another. For example, urainium decays exteamly slowly, having a half life of some four billion years. Therefore it's radiation is very weak and cannot penetrate human flesh, however, it can still be inhaled.Potassium40 is possibly the most common radioactive material that enters your body- it is well coupled to ordinary potassium, and apparently does no great harm. C14 would be another one.these are known as cosmogenic nuclides, because they are made radioactive by hard radiation from space. (Q does K40 belong to the group?)
The explanation is the effect of ionizing radiation on tissues and materials.Three uses are:- sterilizing of instruments and parapharmaceutic items- diagnostic with radioactive isotopes (scintigraphy)- treatment of cancers with radioactive isotopes
Radioactive iodine is taken up by the thyroid gland because it is the only tissue in the body that can absorb and store iodine to make thyroid hormones. Other tissues do not have this ability, so they are not affected by radioactive iodine treatment.
Radiation can enter the body through exposure to sources like X-rays, gamma rays, or radioactive materials. It can penetrate the skin and tissues, reaching internal organs and causing damage at the cellular level. Accidental exposure or prolonged contact with radioactive materials can pose risks to health.
No. They will contain abnormal cells and cancer if implanted.
Gymnosperms transport materials through vascular tissues.
Because water, minerals and prepared food materials are conducted (transported) through these tissues.
