How X-rays in matter create genetoxic low-energy electrons

02-Feb-2017

Researchers led by Kiyoshi Ueda of Tohoku University have investigated what x-rays in matter really do and identified a new mechanism of producing low-energy free electrons. Since the low-energy electrons cause damage to the matter, the identified process might be important in understanding and ...
