No, you cannot pass radiation to others after having a nuclear scan. The radioactive substances used in these scans typically have short half-lives, meaning they decay quickly and do not remain in the body for long. After the procedure, any residual radiation is usually minimal and does not pose a risk to others. Your healthcare provider will give specific instructions on safety precautions to follow post-scan.
Neither, a CAT scan is one where computers are used to synthesise an image, but the radiation used is usually X-rays, though positron emission can be used, in this case it will be using appropriate radiation sources. Fusion and fission don't come into it.
Yes, a bone density scan, also known as a dual-energy X-ray absorptiometry (DXA) scan, uses a small amount of ionizing radiation to measure bone mineral density. This radiation exposure is very low and considered safe for most people.
No. If you are considering hair loss as the result of high levels of radiation dose, nuclear medicine scans don't give anywhere near enough radiation to cause that. In fact, most common nuclear medicine scans deliver less radiation than a CT scan.
The amount of radiation is so slight that even the sensitive testicular tissue is at minimum risk.

If a patient is pregnant, it is generally recommended that she not have a kidney nuclear medicine scan. The unborn baby is more sensitive to radiation than an adult. If a woman thinks she might be pregnant, she should inform her doctor.
The scan that is not nuclear is typically referred to as an MRI (magnetic resonance imaging) scan. It uses a magnetic field and radio waves to create detailed images of organs and tissues in the body.
No, you can't. The high energy photons pass through you, and will do some damage to the tissues of your body because they are ionizing radiation, but you will not be able to feel it.
Doesn't it make you wonder why these radiation questions have not been answered??
They scan your boarding pass because, after 9/11, you cannot go through security to the gate area unless you have a boarding pass.
the kidney nuclear medicine scan is unique in that it reveals how the kidneys are functioning. This is valuable information in helping a doctor make a diagnosis.
