The track structure of low electron, proton and alpha particle in water as a media has been calculated with Monte Carlo method. The spectrum of DNA damages has been simulated by the track structure model. Then the surviving fraction at different dose level is calculated by connecting track structure and phenomenological dynamic model.

The umbilical cord blood solution, which the DMSO concentration is 1.0M, 1.5M and 1.75M,was confected. The solution was in equilibrium for 20 minutes. Then, the umbilical cord blood was completely immerged in liquid nitrogen for about 24 hours. Then, the umbilical cord blood was taken out and was warming in the thermostat water bath for 20 minutes. The fraction surviving of the umbilical cord blood was more than 80%.
