Researchers define for the first time the precise exact ranges in which positively and negatively charged fragments can be produced when living cells are bombarded with fast, heavy ions. When living ...

A new study using mass spectrometry is helping piece together what happens when DNA that has been sensitized by the oncology drug 5-fluorouracil is subjected to the ionising radiation used in ...

The International Space Station, like all human habitats in space, has a nagging mold problem. Astronauts on the ISS spend hours every week cleaning the inside of the station's walls to prevent mold ...

Radiation can be defined as energy traveling through space. There are two types of radiation, ionizing and non-ionizing, which are differentiated by how they interact with matter. Non-ionizing ...

Many substances we face today are a by-product of technology. No animals have encountered them before. For example: pesticides and food additives. By contrast, radiation has always been present. The ...

When living cells are bombarded with fast, heavy ions, their interactions with water molecules can produce randomly scattered 'secondary' electrons with a wide range of energies. These electrons can ...
