From page 1...
... The principal concern for flight directors that increased exposure of astronauts to radiation raises is the potential impact on flight schedules and crew rotation if a radiation event pushes an astronaut over an allowable radiation limit. Astronauts are also concerned that crossing an allowable radiation limit will restrict flight opportunities.

... Although this report is directed at NASA, CSSP/CSTR believes that some of its recommendations could also be implemented by mission control-Moscow. SOLAR PARTICLE EVENTS AND THE INTERNATIONAL SPACE STATION Based on the assumption the best now available that the radiation characteristics of the current solar cycle will resemble those of the last cycle, there is nearly a 100 percent chance that at least 2 out of 43 planned ISS construction flights will overlap a significant solar particle event (SPE)

From page 3...
... SPACECRAFT SOURCES OF OPERATIONAL RADIATION DATA Data that could contribute to reducing radiation risk are currently being acquired by a strategically placed multiagency fleet of research and operational spacecraft. This fleet can provide information on the radiation environment of ISS orbit in real time and in advance of real time.

... It should also establish a multidisciplinary steering committee to advise the task force. SPACE WEATHER MODELS APPLIED TO RADIATION RISK REDUCTION The above recommendations address means to exploit currently available resources to allow a rapid augmentation of the tools available for radiation risk management during ISS construction.

... Several of the existing advanced, databased space weather nowcast and forecast codes (see Appendix A) could be transformed relatively quickly into operational codes to give SRAG the ability to forecast at least some radiation-nsk parameters during most of the ISS construction penod.
