Radioactive substances in the environment can harm cells, damage DNA, and cause cancer. If we take gamma rays, they kill living cells upon contact as they have high penetration power. But this doesn't mean that they are totally dangerous and can't be used by living things. We have to see the level of radioactive isotopes used in order to say they are dangerous to others. Low levels of radioactive isotopes is used in a sample and it becomes a tracer by which to detect molecular changes. Melvin Calvin and his coworkers used Carbon 14 to detect all the various reactions that occur during the process of photosynthesis. Radioactive isotopes are being used largely in the medical field. The high level of radioactive isotopes (radiation) has been used to sterilize medicine and dental products for many years. Now, it can be used to sterilize the US mail and other packages to free them of possible pathogens such as anthrax spores. In addition to this, cancer treatment through radioisotopes to destroy only cancer cells, with little risk to the rest of the body is another important use of radioactive isotopes.
Some isotopes are safe while others can be radioactive.
Radioactive isotopes are generally dangerous.
External and internal irradiation.
Yes.
Some imaging uses radioactive isotopes to see various parts of the body.
All radioactive isotopes will disintegrate.
The location of the uptake of the ions can be measured because of the half life of the radioactivity!
Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Sodium has no radioactive isotopes.
Radioactive isotopes are not stable.
Some imaging uses radioactive isotopes to see various parts of the body.
All the uranium isotopes are radioactive.
All radioactive isotopes will disintegrate.
