Don Quixote: "To attain to eminence in letters costs a man time, watching, hunger, nakedness, headaches, indigestions, and other things of the sort."

>Is is being CsTreated since eight years, why we do have radioactive Caesium still accumulating in the coast? As far as I know, this is because about 10 PBq of Cs-137 was released …

There are reasons, why not to do that: 1) DF doesn't add up like that at low concentrations. Then it comes down to selectivity of the material. Sodium and cesium have similar chemi…

Decontamination factor of 100 is rather terrible compared to DF of over 8 million of actual filter materials, which are being used at Fukushima: https://www.fortum.com/sites/g/file…

Hopefully one day ESA will also use radioisotope thermoelectric generators... :( https://en.m.wikipedia.org/wiki/Rosetta_(spacecraft)

I didn't know about those reactors. Interesting. When writing the answer, I didn't even consider, that those reactors need to be fast reactors. In retrospect it is obvious, but mak…

Thanks for correction. Unfortunately I'm not able to edit it anymore.

In fact the fission[1] part in such small scale is hard. Curiosity and other probes using thermonuclear batteries harness alpha decay[2], which is relatively easy as it happens whe…

We were both in a very small school in the countryside and when I was on 5th and she on 6th grade, we had wonderful teacher, Harri Ketamo (Google him and you'll end up wondering, w…

I still remember Kaisa telling in primary school, that Euclid's proof of infinite number of prime numbers is often considered as the most beautiful proof in mathematics.

Curiosity has a battery of 5 kg and it delivers 2 kW thermal and 125 W electric power.

Maybe the biggest drawback for tritium is the decay energy of 0.02 MeV compared to 5 MeV of Pu238. On longer missions also half-life may create problems (12 years / 70 years). E: I…

In Finland the most common reason is, that hardly any suitable rivers exist any more as they have been dammed.

Is there large possibility to find any wrecks on this area?

Nuclear waste is waste because it doesn't contain enough fissile nuclides (i.e. nuclides, which could produce heat in fission). It has almost nothing to do with radioactivity or de…

This article could be applied to the organizers of huge international sporting events like FIFA and Olympic committee. I would love to see the books of those organisations checked.…

Moreover in many countries the taxes are related to CO2 emissions, which will result in savings as well.

I think even one satellite is enough, if you have enough data points. You can tune the clocks based on the signals captured, when the location of the plane was known. After that ea…

I think they would be better off offering Win7 at discounted price. My wife asked me to install Ubuntu on her new laptop after short experiment with Win8 and now she is also trying…

At times like this, I'm reminded of the nuclear power plants of the world and their automation based on punched cards. When speaking about systems, which need maximal reliability a…

Thanks for sharing the link. It was a very good read.
