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 atomic number?

Use the Chart of the Nuclides to determine what kind of γ-radiation 99mTc emits.
