What type of radiation exposure is there in a thyroid scan?
GaleEncyofMedicine
The patient should understand that there is no danger of radiation exposure to themselves or others. Only very small amounts of radioisotope are used. The total amount of radiation absorbed is often less than the dose received from ordinary x rays.

Can radiation cure diseases?
not really, it depends on the level of exposure, some parts of the body are more sensitive to radiation than other parts, for example the thyroid, which can be protected by taking potassium iodide
What is a type of electromagnetic radiation used for medical images?
MRI uses radio waves; a CT scan uses x-rays.
What are three reasons radiation sickness symptoms vary?
Individual sensitivity Radiation dose absorbed type of radiationRadiation sickness varies based on the amount of expsure of radiation and how particular person's body reacts to the radiation poisoning. It also depends on how the radiation poisoning entered the body: Oral, inhalation or total body exposure.
What type of device includes any point source that emit radiation without actively dispersing radioactive material?
Radiological Exposure Devices (REDs)
What is a radiation exposure why is it so dangerous?
Radiation exposure is very dangerous because in your skin, contain cells that contain melanin which is a pigment. Melanin cells determine the color of your skin and when a melanin cells is ready to reproduce to make more the DNA is copied and if your in radiation at the time, the radiation can mutate the DNA and over time, the mutated cell will replicate over and over again which can be considered as a type of skin cancer. So I'd suggest staying out of the suns radiations or use sunblock and re-apply every so often(:

What can be done to lower exposure to radiation?
To reduce exposure try the following:avoiding sources of radiationshielding to block radiationdecontamination if the radiation source is in dust or liquid form on skin and/or clothingiodine tablets to protect the thyroid gland from iodine-131 if presentetc.These will have to be adapted depending on the exact type and source of radiation. For example some sources can't be avoided, shielding that works for one type of radiation doesn't for another, etc.
What factors determine the extent of radiation damage?
The amount of exposure (measured in rads or rems), the duration of exposure, and the type of radiation you are exposted to determine the extent of the damage.
What type of radiation emitted during a nuclear detonation and from fallout results in whole body exposure?
Gamma radiation
What were the sources of radiation exposure in Hiroshima?
The source was the fission type uranium atomic bomb.
Which instrument type would be most beneficial to the responder when entering a field of radiation?
an exposure rate survey instrument
Can iodine help to prevent radiation sickness?
In simple terms, iodine can help someone to avoid radiation damage to the thyroid if that person is exposed to radioactive iodine. Radioactive iodine is one of the fission products that is released in a nuclear meltdown. If this material escapes into the atmosphere, individuals nearby may be exposed and take in radioactive iodine. Since iodine will collect in the thyroid, if iodine is taken before or upon exposure, the iodine a person took will "take up space" in the thyroid and the radioactive iodine won't be able to "move in" and collect in the thyroid and cause radiation damage. Taking iodine is a way to minimize a specific type of radiation poisoning. As radioactive iodine is a fission product, it can only appear as a result of an accident involving spent nuclear fuel. The nuclear meltdown is the most probable cause of the release of fission products, and there are a number of very hazardous fission products other than iodine. It is a good idea to reduce exposure by reducing exposure time, increasing the distance a person is from a source, or setting up some kind of shielding.
What IS the difference between cat and pet scan?
The difference is in the type of radiation used to form the image. A Computed Axial Tomography (CAT) scan can use any type of radiation to create the image, the specific type is not specified in the name, but most often uses X-rays; but a Positron Emission Tomography (PET) scan specifically uses positrons as the radiation form. A third type, Magnetic Resonance Imaging (MRI) uses the miniscule magnetic fields of naturally occurring compounds within the human body to create its images.
How many rads are in a dental X-ray?
The exposure one receives from a radiograph/x-ray at the dentist is dependent upon what type of x-ray is taken and how many. Dental x-rays of any kind are much safer/lower radiation exposure than most medical x-ray exposures, especially including CT scans. CT scan of your head ~ 200 mrem CT scan of the heart ~ 2,000 mrem Dental Bitewing ~ 0.5 mrem (you typically receive about the same or more radiation annually from living in the mountains (closer to outter space) compared to someone at sea level, as you do during a dental x-ray (both of which are typically less than a 1/6th your usual annual exposure to radiation from the environment).)
What type of electromagnetic wave has the shortest wavelenght?
Gamma rays have the shortest wavelength compared to most of other electromagnetic radiation. Gamma rays have high penetrating power and are high in frequency. Exposure to this type of radiation can cause many health complications.
What is an example of proper units for expressing exposure rate?
Exposure to what, exactly? The most common kind of exposure that is used is exposure to electromagnetic radiation, especially in the higher intensities. One SI unit is the Gray (Gy). 1 Gray is equivalent to 1 Joule of energy absorbed by 1 kg of matter. More useful is the SI unit Sievert (SV), which accounts for type of radiation and all other pertinent factors.

MRI uses radio waves; a CT scan uses x-rays.
