External radiation therapy, where the rays are directed from a source outside the body, is the most common mode of radiation treatment.

What are the 2 names of radiation?
There are two main types of radiation: External Radiation External radiation is the most common type of radiation, typically given after lumpectomy and sometimes, mastectomy. Internal Radiation Internal radiation is a less common method of giving radiation. It is being studied for use after lumpectomy.
What is counter radiation?
Counter radiation is the emission of radiation by a material in response to being exposed to external radiation. This phenomenon involves the material absorbing incoming radiation and then re-emitting it in a different form. Counter radiation can influence the overall heat transfer mechanisms in a system.
Energy can enter the earth system from internal sources through convection and from external sources through what?
External sources of energy entering the Earth system include solar radiation and cosmic rays. Solar radiation, the primary external energy source, drives various processes and is essential for sustaining life on Earth. Cosmic rays, though less significant than solar radiation, also contribute to the energy balance of the planet.
What type of radiation is considered an external hazard?
Ionizing radiation, such as gamma rays, X-rays, and beta particles, is considered an external hazard because it can penetrate the body and cause damage to tissues and organs. This type of radiation can come from various sources like nuclear reactors, medical procedures, and industrial activities.
What is hybrid radiation?
Hybrid radiation refers to a combination of different radiation therapy techniques, such as external beam radiation and brachytherapy, used together to treat cancer. This approach allows for more precise targeting of the tumor while minimizing radiation exposure to surrounding healthy tissue.
What happens in external radiation therapy?
In external radiation therapy a beam of radiation is directed from outside the body at the cancer
What are the source of radiation?
Cosmic radiation External terrestrial and internal radiation
Who performs External radiation therapy?
A radiation oncologist
Which radioisotope acts as an external source of ionizing radiation in the treatment of cancer?
Cobalt-60 is the radioisotope that acts as an external source of ionizing radiation in the treatment of cancer.
How is radiation therapy administered?
Radiation therapy is delivered via external radiation or via internal radiation therapy (the implantation/injection of radioactive substances).
Is a person who has been exposed to external radiation by definition radioactive?
No.

Internal Radiation Internal radiation is a less common method of giving radiation. It is being studied for use after lumpectomy.
What are 3 reasons radiation sickness varies?
Radiation sickness varies depending upon duration of exposure, whether it was an internal or external exposure, and the dosage of radiation.
What is External radiation therapy like?
It is like having a bone x-rayed
Does the AM241 and Ni63 present an external radiation hazard to users and maintainers?
False
