Return to Main What does the symbol that marks radioactivity look like?

Why is it strictly forbidden to work in such a way that there is danger of internal contamination (The radioactive source enters the body), While it is legal to a certain degree to expose oneself to external radiation (for instance working close to a radioactive source)

The exposure should always be as little as possible ( the ALARA principle). For an external radiation source there is three main ways to do this. Which?
Method 1:
Method 2:
Method 3:

What is so special about Tc compared to the other elements with approximately the same atom number?

Use a chart of nuclides to determine what kind of [math]\gamma[/math]-radiation 99mTc emits.
