I would like to give you my very welcome to the blog of Natural Radioactivity. You will find useful information here about radioactivity and sources of natural radiation. This information includes scientific articles, videos and other material of special interest. Information about myself and my scientific profile is also available.

I'm a physicist with a Ph.D on natural radioactivity. My Ph.D. Thesis is entitled "Radon concentrations in air, soil and water in a granitic area: instrumental development and measurements". I'm working at the university of Cantabria (Spain) and currently at the SLU university as postdoctoral researcher.

INTERNATIONAL INTERCOMPARISON EXERCISE ON NATURAL RADIATION MEASUREMENTS UNDER FIELD CONDITIONS (Spain, May or June 2011)

INTERNATIONAL INTERCOMPARISON EXERCISE ON NATURAL RADIATION MEASUREMENTS UNDER FIELD CONDITIONS

May or June 2011

Laboratory LaRUC from University of Cantabria, Spain will organize an international intercomparison exercise on natural radiation measurements under field conditions next MAY or JUNE 2011. The exercise will be done in an area with high levels of natural radiation and it will be possible to test different instruments and carry out determinations of radon exhalation rate, radon indoor, radon outdoor, radon in water, radon in soil, external gamma radiation and other type of measurements requested by participants. If you wish to find further information, please gave a look to the next picture or contact this blog or LaRUC (laruc@unican.es

Premio Nobel de Física 2010

Press Release  

(taken from Nobel Prize website)

5 October 2010
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2010 to
Andre Geim
University of Manchester, UK
and
Konstantin Novoselov
University of Manchester, UK
"for groundbreaking experiments regarding the two-dimensional material graphene"

 

Graphene – the perfect atomic lattice

A thin flake of ordinary carbon, just one atom thick, lies behind this year’s Nobel Prize in Physics. Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics.
Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.
Geim and Novoselov extracted the graphene from a piece of graphite such as is found in ordinary pencils. Using regular adhesive tape they managed to obtain a flake of carbon with a thickness of just one atom. This at a time when many believed it was impossible for such thin crystalline materials to be stable.
However, with graphene, physicists can now study a new class of two-dimensional materials with unique properties. Graphene makes experiments possible that give new twists to the phenomena in quantum physics. Also a vast variety of practical applications now appear possible including the creation of new materials and the manufacture of innovative electronics. Graphene transistors are predicted to be substantially faster than today’s silicon transistors and result in more efficient computers.
Since it is practically transparent and a good conductor, graphene is suitable for producing transparent touch screens, light panels, and maybe even solar cells.
When mixed into plastics, graphene can turn them into conductors of electricity while making them more heat resistant and mechanically robust. This resilience can be utilised in new super strong materials, which are also thin, elastic and lightweight. In the future, satellites, airplanes, and cars could be manufactured out of the new composite materials.
This year’s Laureates have been working together for a long time now. Konstantin Novoselov, 36, first worked with Andre Geim, 51, as a PhD-student in the Netherlands. He subsequently followed Geim to the United Kingdom. Both of them originally studied and began their careers as physicists in Russia. Now they are both professors at the University of Manchester.
Playfulness is one of their hallmarks, one always learns something in the process and, who knows, you may even hit the jackpot. Like now when they, with graphene, write themselves into the annals of science.
