The National Council on Radiation Protection and Measurements (NCRP) is a fancy group of people who work together to make sure that everyone is safe from something very dangerous called radiation. Radiation is a type of energy that is given off by some things, like the sun, or even by some machines that doctors use to look inside our bodies.
Now, radiation can be both helpful and harmful. In small amounts, it can help to make certain medicines and treatments. But when someone is exposed to too much radiation, it can be dangerous and cause sickness, or even cancer.
So, the NCRP is a group of very smart people who study radiation, and come up with rules and guidelines to make sure that we are all safe. They tell doctors and scientists how to use radiation safely, and make sure that the machines and devices that we use are not dangerous.
They also keep an eye on radiation levels in our environment, like in the air, water or soil, and make recommendations to keep them at safe levels.
In a way, the NCRP is like a superhero team watching over us all, making sure that we can use the powerful forces of radiation only for good and not for evil.
