The US Radiation Worker annual radiation limit is 5 rem, or 50mSv/year. Divided into the 2000 annual working hours, that’s 0.025mSv/hour.
The Mars Curiosity rover measured an average dosage on Mars of 0.67mSv/day at about -4km altitude. That’s 0.028mSv/hour.
If you worked somewhere lower altitude, like Hellas Basin (-7km or even possibly -8km) or a place like Valles Marineris at -5km and valley walls nearby, you should be able to get that down to the 0.025mSv/hour of US Radiation Worker limits.
The Space Show, hosted by David Livingston at www.TheSpaceShow.com, will have the following guests this week:

Hubble’s public imagery with Zoltan (Zolt) Levay.
Zoltan G. Levay (Zolt) is Imaging Group Lead in the Office of Public Outreach at Space Telescope Science Institute (STScI) in Baltimore, Maryland. Since 1993 he has primarily been responsible for producing publicly accessible images from Hubble Space Telescope [...]
What's older than these ancient trees? Nobody you know -- but almost everything in the background of this picture. The trees are impressively old -- each part of the Ancient Bristlecone Pine Forest located in eastern California, USA. There, many of the oldest trees known are located, some dating as far back as about 5,000 years. Seemingly attached to tree branches, but actually much farther in the distance, are the bright orbs of Saturn (left) and Mars.
These planets formed along with the Ea [...]
Ariane 5 delivered a new record payload lift performance on today’s successful launch from the Spaceport in French Guiana, which orbited a pair of telecommunications satellites at the service of American and Indonesian customers.
This heavy-lift mission carried EchoStar XVIII and BRIsat, and it delivered a total calculated mass of 10,730 kg. into geostationary transfer orbit (GTO) – setting a new launch benchmark for the Ariane 5 ECA version. The total included some 9,840 kg. for the two [...]
Expedition 47 Commander Tim Kopra of NASA, and Tim Peake of ESA and Yuri Malenchenko of Roscosmos landed their Soyuz TMA-19M spacecraft in Kazakhstan at 5:15 a.m. EDT. Russian recovery teams will help the crew exit the Soyuz vehicle and adjust to gravity after their stay in space.
The trio arrived at the International Space Station on Dec. 15, 2015. The crew’s return marks completion of the in-flight portion for NASA human research studies in four categories– ocular health, cognition, sal [...]
Pluto's pitted plains meet rugged highlands in this stunning view. On the left lies a southeastern extent of the bright region still informally known as Sputnik Planum. At right the edge of a dark region, informally Krun Macula, rises some 2.5 kilometers above the icy plains. Along the boundary, connected clusters of large pits form deep valleys, some over 40 kilometers long with shadowy floors. Nitrogen ice is likely responsible for the more reflective plains.
The dark red color of the high [...]
At 9:20 a.m. EDT, NASA astronaut Jeff Williams assumed command of the International Space Station from astronaut Tim Kopra of NASA in a traditional Change of Command ceremony. Expedition 48 will officially begin under Williams’ command when the Soyuz spacecraft carrying Kopra, Tim Peake of ESA (European Space Agency) and Russian cosmonaut Yuri Malenchenko undocks from the space station early Saturday morning.
Their return will mark the end of 186 days on board the station for the trio. [...]
