Means of anticipating frequency of emissions are examined in connection with space exploration by man; fairly reliable estimate of maximum sunspot number at peak of next cycle (1969) will be available in 1965 or 1966; on basis of means considered, it appears impossible to guarantee non-encounter with solar cosmic rays in space flights lasting longer than 4 days; for longer durations, radiation shielding appears only feasible approach to safety at time of high sunspot number.
