The most well known is using x rays to see whether bones are broken. The broad area of x-ray use is called radiology. Within radiology, we find more specialized areas like mammography, computerized tomography (CT), and nuclear medicine (the specialty where radioactive material is usually injected into the patient).
Q. What are the advantages of radiation?
The main advantage of radiotherapy is that it may help to control the growth of the cancer. For a small number of people with borderline resectable cancer and locally advanced pancreatic cancer, radiotherapy may help to make surgery possible.

Q. How is radiation used in medicine?
Nuclear medicine procedures help detect and treat diseases by using a small amount of radioactive material, called a radiopharmaceutical. Some radiopharmaceuticals are used with imaging equipment to detect diseases. Radiopharmaceuticals can also be placed inside the body near a cancerous tumor to shrink or destroy it.
Q. What does Gold radiation do?
First, gold is capable of absorbing radiation at a significantly higher rate than tissue: up to about 100 times more for keV energies (2). Second, gold nanoparticles that interact with radiation can release extra electrons via the Auger effect. The Auger effect occurs when an atom releases electrons postionization.
Q. Does iron block radiation?
Any material provides some shielding. Common shielding materials are iron, concrete, lead, and soil. Scientists measure the shielding ability of a material by determin- ing the thickness of the material required to absorb half of the radiation from a given source.
Q. What are the principles of radiation protection?
Three principles for radiation safety: time, distance, and…
- Time. Radiation exposure can be accumulated over the time of exposure.
- Distance. A greater distance from the radiation source can reduce radiation exposure.
- Shielding.
Q. How good is water at blocking radiation?
It is used for neutron radiation because water does a good job of slowing down neutrons. Slowing down neutrons can stop them from leaving the shield and also slow down enough to cause fissions. Fissions are what power nuclear reactors. This is why most reactors are located in a pool of water.
Q. Does Ice protect from radiation?
Yes ice can shield radiation. It takes about 10 inches (25 cm) of ice to reduce neutron radiation to 1/10 it’s initial dose (read as tenth thickness). It actually is very good at neutron radiation, however for cosmic rays it is not as effective.
