Radiation Research, Vol. 175, No. 1 (January 2011), pp. 21-28 (8 pages) Little is known about the effects of space radiation on the human body. There are a number of potential chronic and acute ...

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 ...

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 ...

CT scans diagnose afflictions from tumors to kidney stones to life-threatening diseases and injuries, such as aneurysms and blood clots leading to stroke. But the radiation emitted by this essential ...

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 ...

The anti-cancer drug 5-fluorouracil (5FU) acts as a radiosensitizer: it is rapidly taken up into the DNA of cancer cells, making the cells more sensitive to radiotherapy. A new study using mass ...
