Okay kiddo, so when we talk about nonradiation condition, we're talking about a situation where there isn't any radiation going on. Radiation is like invisible energy that can come from things like the sun or nuclear reactions, and it can be harmful to people if they're exposed to too much of it.
So when we say that there's a nonradiation condition, it means that we're making sure that no radiation is present in a certain area. Scientists and engineers might use this term a lot when they're working with sensitive equipment or doing experiments that could be affected by radiation.
To make sure there's a nonradiation condition, they might use something called a radiation shield, which is like a big, strong box that can block out the radiation. They might also use special sensors to make sure that no radiation is getting through.
Overall, the nonradiation condition is all about keeping things safe and making sure that radiation isn't turning up where it shouldn't be.
