I work in the railway safety domain.

There are EMC (ElectroMagnetic Compatibility) standards very strict about how to manage equipment producing EMC variable fields. These standards are based on scientific evidence and have the goal of protecting human people from adverse effects of radiations. If we talk about non-ionizing radiation the only effect they can cause is heating our body, which is dangerous for our brain especially. In usual situations the exposure to such risk is negligible, nevertheless suppliers have to demonstrate that their system are fully compliant to above standards.

There's also the EMI problem (ElectroMagnetic Interference). This is about the impact your system can have on people having medical devices. As they're very sensitive to EMC fields usually you also have to put signals on places where such risk is not negligible.

Then there is the way we all do "risk assessment" in our life which is usually very far from being rigorous 😁

Risk is a combination of hazard likelihood and hazard severity. You cen have low likelihood but high severity that leads to high risk or high likelihood and low severity which also leads to high risk.

If you could rigorously estimate the risk you're exposed to in your life you'd be much more worried by that small, lovely, glass of wine (which is a class A carcinogenic) than a huge power line next to your home 😁
