Radiation Induced DNA Damage and Related Bio-chemi-physical Problems

Some of recent works are presented on radiation induced DNA damage being carried out at China Institute of Atomic Energy (CIAE) and related bio-chemi-physical problems. Emphasis is placed on track structure and its relation to the cell end-point, and a simple model proposed to study the dynamical behavior of P53-Mdm2 interaction which plays pivotal role in cellular response to DNA damage.
