What jobs work with radiation?
A number of qualified professionals work together to deliver cancer care through radiation therapy: Radiation Oncologists, Radiation Therapists and Medical Physicists.
- Radiation Oncologist.
- Radiation Therapist.
- Medical Physicist.
What are some uses of gamma radiation?
Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry. Shielding against gamma rays is essential because they can cause diseases to skin or blood, eye disorders and cancers.
Where are gamma rays most commonly used?
The most common gamma emitter used in medical applications is the nuclear isomer technetium-99m which emits gamma rays in the same energy range as diagnostic X-rays.
How are gamma rays used in the medical field?
Gamma rays are widely used in medicine and specifically in the area of oncology to treat malignant and cancerous tumors during a process called gamma knife surgery. In this type of treatment, concentrated beams of gamma rays are directed at tumors in order to kill cancerous cells.
What do gamma rays do to humans?
Gamma rays have so much penetrating power that several inches of a dense material like lead, or even a few feet of concrete may be required to stop them. Gamma rays can pass completely through the human body; as they pass through, they can cause ionizations that damage tissue and DNA.
What job is exposed to the most radiation?

How is gamma radiation used in medical applications?
A gamma knife is a specific type of gamma irradiation used to kill cancerous cells in the brain. The head is clamped into a special helmet to make sure it stays perfectly still during the irradiation. In medical applications that involve using radioactive sources, efforts are made to ensure that irradiation does not cause any long-term effects.
What are some common sources of gamma radiation?
What are some common sources of gamma radiation? Gamma radiation is released from many of the radioisotopes found in the natural radiation decay series of uranium, thorium and actinium as well as being emitted by the naturally occurring radioisotopes potassium-40 and carbon-14. These are found in all rocks and soil and even in our food and water.
What kind of radiation is used in radiosurgery?
There are 3 types of radiosurgery. Each type uses different equipment and radiation sources. Cobalt60 systems use cobalt as a source for gamma rays. This type of system is commonly referred to as the Gamma Knife. The Gamma Knife is not really a knife at all.
What kind of work does a radiation oncologist do?
Radiation oncologists work closely with other medical specialists, especially surgeons, medical oncologists and palliative care physicians, as part of a team caring for patients with cancer. Radiation oncologists also work closely with radiation oncology medical physicists and radiation therapists to plan and deliver radiotherapy.
