The first chapter provides background information about the dynamic radiation environment experienced at ISS and summarized radiation health and protection requirements for activities in low Earth orbit. The introduction describes the suits and presents goals of several experiments performed with them. This publication describes recent investigations that evaluate radiation shielding characteristics of NASA's and the Russian Space Agency's space suits.

This finding provides mechanistic evidence to support the increased prosthetic joint infection rates observed in clinical studies. Space suits cause increased PER and MER compared with standard surgical clothing. One experiment showed inconsistent results, with a trend toward increases in both PER and MER when space suits are used compared with standard surgical clothing. Four experiments consistently showed statistically significant increases in both PER and MER when space suits are used compared with standard surgical clothing. An Andersen impactor was used to sample bacteria, with culture counts performed at 24 and 48Â hours. Particle counts were analyzed with 2 separate particle counters capable of detecting particles between 0.1 and 20 Î¼m. A comparison of emission rates between space suits and standard surgical clothing was performed in a simulated surgical environment during 5 separate experiments.

This study aimed to compare the particle and microbiological emission rates (PER and MER) of space suits and standard surgical clothing. Recent evidence suggests that space suits may in fact contribute to increased infection rates, with bioaerosol emissions from space suits identified as a potential cause. The role of space suits in the prevention of orthopedic prosthetic joint infection remains unclear. Vijaysegaran, Praveen Knibbs, Luke D Morawska, Lidia Crawford, Ross W
