Which radioactive element is used in the treatment of blood cancer?
The correct answer is Cobalt - 60. Cobalt - 60 radioisotopes are used in the treatment of blood cancer [leukemia].
How does radium help treat cancer?
Radium targets bone cancer cells. This is because it is similar to calcium, which is also absorbed by bone cells. The cancer cells in the bone take up radium 223 and it then releases radiation which travels a very short distance. This means that the cancer cells receive a high dose of radiation which can destroy them.
How can gamma rays be used to treat cancer?
Use and importance in clinical medicine Gamma rays can kill living cells and damage malignant tumor. The Gamma radiation intensity decreases exponentially with the depth of penetration. They damage the cancerous cells' DNA, causing them to die or reproduce more slowly.

How is radiation given?
Radiation therapy can be given in 3 ways: 1 External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. It's usually given over many weeks and sometimes will be given twice a day for several weeks. A person receiving external radiation is not radioactive and does not have to follow special safety precautions at home. 2 Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. With some types of brachytherapy, radiation might be placed and left in the body to work. Sometimes it is placed in the body for a period of time and then removed. This is decided based on the type of cancer. Special safety precautions are needed for this type of radiation for a period of time. But it's important to know if the internal radiation is left in the body, after a while it eventually is no longer radioactive. 3 Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.
Why do doctors recommend radiation therapy?
If your cancer care team recommends radiation treatment, it’s because they believe that the benefits you’ll get from it will outweigh the possible side effects. Still, this is your decision to make. Knowing as much as you can about the possible benefits and risks can help you be sure that radiation therapy is best for you.

What are the elements used to treat cancer?
What Radioactive Elements Are Used to Treat Cancer? Cobalt and cesium are commonly used in high-energy photon beams. This is the most common form of radiation used for cancer treatment. These elements are used in a machine called a linear accelerator, which delivers radiation to a specific location in the body.

How long does iodine last?
Iodine has a half-life of eight days, strontium has a half-life of 29 years, and cesium has a half-life of 30 years. Isotopes strontium-90 and cesium-137 are still present, making the area toxic and uninhabitable. Radioactive iodine is linked to thyroid cancer, and strontium can cause leukemia. Cesium has spread the farthest and lasts the longest.
Is polonium 210 radioactive?
The radioactivity of an element depends on what isotope is present. Polonium-210 is regarded as an extremely volatile, dangerous, and radioactive isotope. By mass, polonium-210 is nearly 250,000 times more toxic than hydrogen cyanide. To put that into perspective, hydrogen cyanide was used as a chemical weapon in World War I. It interferes with the normal function of oxygen in nearly every organ of the body, causing rapid death in under a minute.

Does strontium cause leukemia?
Radioactive iodine is linked to thyroid cancer, and strontium can cause leukemia. Cesium has spread the farthest and lasts the longest. It also affects the entire body, with particular harm done to the liver and spleen.
How does radiation kill cancer cells?
Radiation therapy kills cancer cells by damaging their DNA to the point that they can no longer divide indefinitely (so they can no longer harm us). Yet random radiation damage to healthy cells may cause mutations that can result in clones of cells that will divide indefinitely (i.e. become cancerous). Radiation Induced cancers have always been a potential risk of radiation therapy (or CT scans, dental x-rays, sun (UV) exposure, tanning beds, etc.). Any time there are ionizations produced in or near molecules of DNA, that risk exists.
What is radiation treatment?
Radiation is one of many forms of cancer treatments like surgery, chemotherapy, etc. Radiation kills cancer cells. It is directed precisely on the cancer cells.
What are the treatments for cancer?
The elements vary greatly depending on the doctor, tumor location, type of cancer, size of patient, and doctor or facility a person employs. Energy in the form of photons, electrons, and protons are commonly used to treat the various forms of cancer whether it be skin, blood, or solid tumor. There may be more than one treatment plan as the fields are sometimes coned down during a course of treatment. The energy, type of treatment, and total radiation dose will vary as well. Intensity modulation, robotic radiosurgery, external beams, internal implants, and high dose brachytherapy are all commonly used. Treatment centers may or may not have access to all of these modalities so individuals with same stage of cancer and diagnosis may be treated differently. A person may want to do some research to determine where they will want to be treated to try to have the best possible outcome and to avoid any unwated side effects.
How to reduce the risk of secondary cancer?
The main way we have to reduce the risk of inducing secondary cancers is to limit the number of cells exposed to radiation. The greatest advance we have had in our ability to accomplish this is to give ionizing radiation with Proton Beam Therapy as opposed to X-rays. The difference between getting a course of radiation therapy with x-rays (Intensity Modulated Radiation Therapy) as opposed to protons is roughly the same as getting 450,000 dental x-rays. Numerous studies, published in peer-reviewed journals show a lower incidence of radiation induced cancers (both theoretical and epidemiological) with proton therapy as opposed to IMRT.
