Caution : fire risk !
Robin des Bois and GEIDE post-disaster
Nobody can be blamed for the outbreak and consequences of earthquakes of large magnitude. For forest fires, it’s a different story. Only the lightning escapes human responsibility. Man is the cause of more than 9 out of 10 forest fires.
Barbecues, gas stoves, cigarettes, motorcycle incursions, quadbikes or other vehicles with internal combustion engines, campfires, fireworks and combustible wastes are all risks of fire in an environment that is vulnerable to conflagration. A spark can ignite thousands of acres and a small fire can in a few seconds become uncontrollable.
Plutonium for Martians
Whatever life forms are on planet Mars, they will have to deal with plutonium-238 produced by American atomic research labs if the Mars Science Laboratory Curiosity mission succeeds. The launch is scheduled for Saturday, November 26th from Cape Canaveral, Florida.
The plutonium-based radio-isotopic generator that powers the Curiosity robot will become an out-of-commission vehicle on the Martian surface after 23 months of activity and exploration. It will leave a lot laboratory waste and its 4.6kg of 238Pu. The half-life of 238Pu is 87.7 years. 264 years after its production, it gives off another 12.5%. If Mars is the subject of colonization experimental within the next century, pioneers risk being exposed to radioactive contamination of human origin dating from 2012 or 1975 with the landing of the Viking probes. Do not forget that the surface and the atmosphere of Mars have been poisoned by at least 5 other crashed probes each powered by a plutonium battery amounting to hundreds of grams.
