More than two billion tons of cargo pass through ports and waterways annually in the United States. Many ports rely on gamma-ray scanners, based on radioactive isotopes such as cobalt-60, to screen cargo for nuclear materials or weapons.
Sure, the periodic table of elements is useful. But wouldn't it be better if we all had an illustrated version that depicts different items made from each element?
Great resource, however I think it is still missing some items in the lanthanides (e.g. Nd magnets etc)

In the first 300 days of the Mars Science Laboratory surface mission, the Curiosity rover cruised around the planet's Gale Crater, collecting soil samples and investigating rock structures while the onboard Radiation Assessment Detector made detailed measurements of the radiation environment on the surface of Mars.
SwRI scientists published radiation surface dose rates from the first 300 days on Mars in Science online Dec. 9. Curiosity's Radiation Assessment Detector observed a spike in the radiation dose associated with one hard solar energetic particle event and three dips in radiation associated with soft interplanetary coronal mass ejections, which provided magnetic shielding against galactic cosmic rays. Occasional brief gaps are typically when RAD was powered off to minimize interference with other activities.
"Our measurements provide crucial information for human missions to Mars," said Dr. Don Hassler, a Southwest Research Institute program director and RAD principal investigator. Hassler is the lead author of "Mars' Surface Radiation Environment Measured with the Mars Science Laboratory's Curiosity Rover," scheduled for publication in the journal Science online on December 9, 2013. "We're continuing to monitor the radiation environment, and seeing the effects of major solar storms on the surface and at different times in the solar cycle will give additional important data. Our measurements also tie into Curiosity's investigations about habitability. The radiation sources that are of concern for human health also affect microbial survival as well as the preservation of organic chemicals."
Two forms of radiation pose potential health risks to astronauts: a chronic low dose of galactic cosmic rays (GCRs) and the possibility of short-term exposures to the solar energetic particles (SEPs) associated with solar flares and coronal mass ejections. The radiation on Mars is much harsher than on Earth for two reasons: Mars lacks a global magnetic field and the Martian atmosphere is much thinner than Earth's, providing little shielding to the surface.
This environmental factor poses a challenge for future human exploration of Mars and is also important in understanding both geological and potential biological evolution on Mars. Both GCRs and SEPs interact with the atmosphere and, if energetic enough, penetrate into the Martian soil, or regolith, where they produce secondary particles that contribute to the complex radiation environment on the Martian surface, which is unlike anything on Earth.

An article by CERN's DG R.-D. Heuer. Worth reading all aspects of it.
Millennia ago, and 26,000 light years distant in the dim and somewhat unremarkable constellation of Circinus, a monster was born. And when that happened, it gave out a heck of a birth cry.
