I am a little confused and a lot concerned as to why the radioactive decay of elements is considered a difficult concept to grasp. All organic matter breaks down. Each element has its own rate of decay. Uranium has the longest rate, spanning 100s of thousands of years.
What is being taught in the schools today re: Science? The construction of the elements, their properties, including radioactive decay were all part of my high school Science education. Are students not being taught the Periodic Table of Elements and what constitutes the known elements on Earth?
