If you are receiving radiation treatment for cancer, you can still be around kids. The radiation, and the cancer, are not contagious.Another Answer:It depends on whether you just receive radiation, or if you have radioactive implants. If you just receive radiation therapy, such as gamma radiation from Cobalt-60, then you are not radioactive when you leave the facility. If you have implants, however, such as around the prostate gland in certain forms of therapy, you are radioactive, and you need to ask your radiation technologist and doctor what your limits are relative to being around children.Note: Some radiation treatment, particularly neutron bombardment, can cause activation of some of your atoms into a radioactive form. To be safe, talk to your doctor, etc. in any case.Also, bone scans, heart scans, and other types of scans where you are injected with a radioactive tracer, such as Technicium-99M, do make you radioactive for a short while, often just a few days. Again, talk to your doctor.
Some common uses of technetium include medical imaging, specifically in the form of radioactive isotopes for bone scans and heart imaging exams. Technetium is also used in industrial applications, such as measuring the thickness of materials and detecting leaks in pipelines. Additionally, it is used in scientific research and as a tracer in environmental studies.

Radionuclide bone scans. These scans involve injecting a small amount of radioactive material into a vein. Primary tumors or cells that have metastasized absorb the radioactive material and show up as dark spots on the scan.
There is a particular area of bone that is much more metabolically active than the bone in the rest of the body.
Cells account for only 2% of the weight of a typical bone cell.
