title: [Dynamics of radiation environment of space station "Mir" by the "DOZA-A1" readings].
abstract: One of the serious disadvantages of the U.S. (AP-8 and AE-8) and Russian trapped radiation models is the lack of data concerning the dynamics of trapped particles fluences within a time interval shorter than the solar cycle. The available models are capable to predict the energy spectra of trapped particles only for periods in the vicinity of the solar minimum or maximum. The current models are also lacking data about the angular distribution of trapped particles. Meanwhile, these facts are important in conjunction with the problems of radiation safety of space crews. DOZA-A1 incorporating 7 semiconductor detector with a dose sensitivity of 2.4. 10(-4) muGy/pulse and a temporal resolution of 15 seconds, and a reading and charging unit were delivered to MIR in September, 1995; the experiment began in January, 1996. Measurements were made in three locations of the basal module. The articles deals with the analysis and comparison of experimental data with results of other dosimetric determinations and predictions of the trapped radiation models.
