Understanding Radiation Survey Equipment Accuracy Levels

When it comes to radiation survey equipment, precision isn’t just a fancy word—it’s a vital part of keeping everyone safe. So, you might be wondering, "What level of accuracy is needed for this equipment?" Well, it’s set at an industry standard of ±20%.
