According to international commission for radiation protection radiation dose uptake should be guided by the following
- Justification: advantages must outweigh the disadvantages.
- Limitation: individual should be protected from radiation dose limits.
- Optimization: Radiation doses should all be kept as low as reasonably achievable. This means that it is not enough to remain under the radiation dose limits. As permit holder, you are responsible for ensuring that radiation doses are as low as reasonably achievable, which means that the actual radiation doses are often much lower than the permitted limit.
