Accident dosimetry and radiation measurement techniques form a critical subset of radiation monitoring, enabling the reconstruction of absorbed doses following unplanned radiological events. These ...

In this lesson, students will investigate the nature of radioactivity and the effect of both distance and shielding materials on different radioactive sources using a Geiger-Muller tube with a counter ...

A new algorithm has been developed to simultaneously estimate multiple shortwave radiation components using data from China's Fengyun-3F satellite. This innovative approach significantly improves the ...

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has successfully exported its proprietary radioactivity measurement standard to Thailand. This milestone marks a ...

A concentration of one part per billion is like a pinch of salt in 10 tons of potato chips—and scientists can now find radioactive particles at concentrations millions of times smaller. In the Journal ...

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new and faster method for detecting and measuring the radioactivity of minuscule amounts of radioactive ...

Twenty-five years ago, the IAEA formed a worldwide network of analytical laboratories to increase global expertise in radioactivity measurement in the environment. Today, the network of Analytical ...

The levels of activity in radiopharmaceuticals that are administered clinically are governed primarily by the need to balance the effectiveness and the safety of the medical procedure by choosing the ...

Background radiation is the invisible radiation that is always present in our environment. It comes from a variety of sources, both natural and man-made. Natural sources include cosmic rays from space ...

This Japanese device turns your smartphone into a nuclear radiation detector for just $70 (Bantan et al., 2026, Radiation Measurements, CC BY-NC-ND 4.0 ) Researchers at Hiroshima University in Japan ...
