All types of radiation become less intense as they travel further away from the radioactive material. This is because the particles or rays become more spread out. The thicker the substance, the ...

He had a Geiger counter nearby to measure radioactivity. When he was finished, he took the polonium away, but something strange happened. The Geiger counter kept clicking, sensing radioactivity.

Her groundbreaking work in radioactivity laid the foundation for numerous advancements in science and medicine. This blog post explores the life and legacy of Marie Curie, highlighting her ...

Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium ...
