Positively charged particles and free electrons are left behind after the collisions. Devices that are used to detect radioactivity are based on the ionizing ability of radiation. One such device is ...

THERE still exists considerable uncertainty regarding the amount of radioactive elements present in sea water, the values found by different investigators varying between very wide limits.

The IAEA's Marine Radioactivity Information System (MARIS) allows free access to users to search and download the results of measurements of radioactivity in seawater, biota, sediment and suspended ...

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 ...

Led by a team from Paris-Saclay University in France, the study researchers found the radioactivity to be well below levels that would be considered hazardous – less than two-hundredths of the safety ...

This publication provides information on the implementation of quality assurance and quality control programmes for the measurement of radioactivity related to the practice of nuclear medicine. It is ...

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 ...

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.
