The FLUKA Monte Carlo transport code is widely used for fundamental research, radioprotection and dosimetry, hybrid nuclear energy system and cosmic ray calculations. The validity of its physical models has been benchmarked against a variet...
Radiation-induced bystander effect and adaptive response in mammalian cells [0.03%]
哺乳动物细胞的辐射旁效应及适应性反应研究进展
H Zhou,G Randers-Pehrson,C A Waldren et al.
H Zhou et al.
Two conflicting phenomena, bystander effect and adaptive response, are important in determining the biological responses at low doses of radiation and have the potential to impact the shape of the dose-response relationship. Using the Colum...
Simultaneous measurement of multiple radiation-induced protein expression profiles using the Luminex(TM) system [0.03%]
