"SPACE RADIATION DOSIMETRY- FROM SEA LEVEL TO INTERPLANETARY SPACE"
The performance of space radiation dosimetry is essential to the construction of predictive models, accurate environment specification for cost-effective design and the interpretation of in-flight performance, including anomaly troubleshooting. Whilst this is an issue which dates back to the dawn of the space age, the new realities as we enter the next millennium include the long term presence of man in space, the increasing use of high performance and susceptible commercial off-the-shelf technology, increased dependence on space systems and a possibly very severe period of maximum solar activity. Following a review of those aspects of the environment and its interactions for which we require dosimetry, recent results will be presented ranging from the atmosphere, through the radiation belts to interplanetary space. Implications for models of radiation environment effects will be discussed together with a consideration of future needs and the prospects for their fulfillment.
