Abstract:
The Pille thermoluminscent passive dosimeter developed by MTA EK is present on the ISS since 2003. Over 21 years of Pille 15- and 90-minutes automatic measurements and 11 years of extra vehicular activity (EVA) dose rates are presented. The 15 minutes long measurements show the possibility to use Pille for spatial mapping of the radiation field and we separate the South-Atlantic Anomaly excess doses from the rest of the orbit. We analyze the results in 3 aspects: the altitude-dose rate correlation, the extra vehicular activity (EVA) excess doses, and the solar cycle caused oscillations in our data.
The results show weak statistical correlation between the altitude and dose rates, and an inverse correlation between dose rates and sunspot numbers. We show that the doses during EVAs are not directly linked to the SAA, and we need to factor in the location of the reference dosimeter inside the ISS and their location on the spacesuits.
