... It outlines, in general terms, the commitment of resources that NASA should make to carrying out these experiments in order to design effective shielding in time for a possible mission launch to Mars by 2018, which would allow for energetically favorable flight trajectories. Chapter 5 addresses additional issues pertinent to carrying out studies on the effects of radiation, and the appendixes provide additional details and clarification as appropriate.

... 4. To estimate the cancer risk posed by exposure of humans to radiation such as HZE particles, for which no human data are available, it is necessary to use data on the Japanese atomic bomb survivors exposed to acute low-LET radiation and then extrapolate, based on experimental data, to estimate the risks posed by high-LET radiation.

... The research priorities recommended by the task group include extensive physical and biological experiments, including animal studies using light and heavy nuclei up to 1 GeV/ nucleon. Such experiments could take more than 20 years at NASA's present utilization rate of approximately 100 hr/yr of accelerator time at Brookhaven National Laboratory's Alternating Gradient Synchrotron (AGS)

... emphasized the need for a dedicated HZE particle facility. The fact that the present report reaches conclusions similar to those in the 1989 report of the National Council of Radiation Protectioni2 underscores the need for additional resources and facilities in order to understand quantitatively the radiation biology associated with interplanetary flights.
