The elements with atomic number greater than 82 are radioactive.The is a measure of how quickly on average a radioactive nuclei will take to decay.Meteorites are among the oldest objects we know about - formed about 4.5 billion years ago. This article describes the principles and methods used to make that determination.There are well-known methods of finding the ages of some natural objects.

Other isotopes with fewer protons in their nucleus are also radioactive.

Since gamma radiation has no charge its path does not bend.

The diagram below shows what materials can block each type of radiation.

The radioactivity corresponds to the neutron/proton ratio in the atom: The neutron/proton ratio for a certain element must fall within a certain range for the element to be stable.

That’s why some isotopes of an element are stable and others are radioactive.Notice it's easy to block alpha radiation (paper will do!
