In medicine, radioactive elements are used for diagnostic imaging (such as PET scans) and cancer treatment (radiation therapy). In industries, radioactive elements are used in various applications like measuring material thickness, detecting flaws in structures, and sterilizing medical equipment.
A point source that emits radiation without actively dispersing radioactive material is typically found in radiation therapy devices, such as linear accelerators used for cancer treatment, or in certain types of industrial radiography equipment. These devices focus and direct radiation beams toward a specific target area, without spreading radioactive material around.
Beta rays are commonly used in medical imaging and cancer treatment, as well as in industrial applications for thickness gauging and quality control. They can also be used in radiation therapy to target and destroy cancer cells.
In internal radiation therapy a source of radioactivity is surgically placed inside the body near the cancer
Gamma rays can cause cancer by damaging the DNA within cells, leading to uncontrolled growth. In cancer treatment, gamma rays are used in radiation therapy to target and kill cancer cells. The high-energy radiation helps to destroy cancer cells and shrink tumors.
The radioactive decay of radon is used in radiation therapy for cancer treatment. Radon isotopes emit alpha particles which can be directed towards cancerous cells to kill them. This targeted radiation therapy helps in shrinking tumors and reducing cancer cell growth.
Yes, radioactive isotopes are largely used for the treatment of cancer.
Adjuvant therapy is used to decrease the chances that cancer will recur.
Radioactive isotopes can be used in radiation therapy to target and destroy cancer cells. The isotopes are directed at the tumor site, where their radiation damages the cancer cells and inhibits their growth. This helps to shrink or eliminate the tumor and treat the medical problem.
With the help of Gene therapy we can replace or supress the cancer gene
Radiation Therapy is therapeutic. This means that radiation is used to treat cancer and some other diseases. Although there is some overlap, Nuclear Medicine is primarily diagnostic in nature which means that radioactive isotopes are used to make a diagnosis.

Radium is a radioactive element that emits radiation, which can damage cells and DNA. This property has been harnessed for cancer treatment in the past, as targeted radiation therapy can be used to kill cancer cells. However, due to its high toxicity and potential harm to healthy cells, radium is no longer commonly used in cancer treatment.

Now, polonium is not used in medical treatment.
