Dose Equivalent, Absorbed Dose and Charge Spectrum Measurements Made in the International Space Station Orbit
نویسندگان
چکیده
Particle intensity, dose equivalent and absorbed dose have been measured on board the space shuttles during their visit to the International Space Station (ISS) on STS-108 and STS-112. The dose estimates are based on very accurate measurements of recoils produced in CR-39 by cosmic ray primary and secondary protons and heavier nuclei and by secondary neutrons. The corresponding LET spectra were used to determine dose equivalent and absorbed dose values for both missions. Estimates of the total flux of Z≥2 nuclei have been undertaken and a charge spectrum was measured for both missions. Comparisons are made with the predictions of a cosmic ray transport model.

External radiotherapy is used for treatment of various types of cancers. Due to the impossibility of measuring the absorbed dose delivered to different organs during irradiation, treatment planning systems (TPSs) have been utilized for calculation of absorbed dose before a radiotherapy procedure. Thus, the accuracy and precession of the TPS is essential.The aim of this study is investigation of...

Background: Annual patient effective dose equivalent can be considered as a quantitative physical parameter describing the activities performed in each nuclear medicine department. Annual staff dose equivalent could be also considered as a parameter describing the amount of radiation risk for performing the activities. We calculated the staff to patient dose equivalent ratio to be used as a phy...
