Post Irradiation Examination

When things get really hot or exposed to radiation, we want to make sure they're still safe and working properly. So, scientists and technicians examine these things really closely to see if anything bad happened to them.

This is called a "post irradiation examination". Think of it like a check-up for something that has been exposed to heat or radiation.

For example, after a nuclear reactor has been in operation for a while, scientists will take some pieces out of it to see how they have been affected by the radiation. They might look at the metal and see if it's still strong or if it has become weak. They might also examine the fuel rods to see if they have any damage or if there is any risk of leaking radioactive material.

Overall, post irradiation examination is a way for us to make sure that things are still safe and functioning properly after being exposed to high levels of heat or radiation. It helps scientists and engineers learn more about how materials handle extreme conditions so that they can make better and safer technology in the future.
