Minimal Risk
The concept of minimal risk is especially influential in the US debate, not least because it is enshrined in the so-called Code of Federal Regulations containing rules governing research on human subjects.. The concept of minimal risk also has a crucial status in Art.17 II of the Convention on Human Rights and Biomedicine of the Council of Europe.
