Num relatório que será entregue à Agência Internacional de  Energia Atômica (AIEA), Tóquio admite que estava &quot;despreparado&quot; para enfrentar  um desastre nuclear. &lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt; &lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;color: lime; font-family: inherit;&quot;&gt;&amp;nbsp;Segundo a agência reguladora do setor no Japão, a radiação emitida por  Fukushima na semana seguinte ao tsunami é sete vezes maior do que a produzida  pelo acidente na usina nuclear de Three Mile Island, nos Estados Unidos, em  1979. Mas a emissão de partículas no território japonês - estimada em 770 mil  terabecquerels - foi equivalente a apenas 15% da descarga radioativa ocorrida no  desastre de Chernobyl, na Ucrânia, em 1986.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;color: lime; font-family: inherit;&quot;&gt; &lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;color: lime; font-family: inherit;&quot;&gt;&amp;nbsp;Quase três meses após o desastre natural que matou cerca de 24 mil pessoas no  Japão, a usina de Fukushima continua emitindo radiação. Mais de 80 mil moradores  do entorno da central nuclear, num raio de 20 quilômetros, deixaram suas  residências. O porta-voz do governo, Yukio Edano, afirmou que mais retiradas  estão sendo consideradas, pois monitoramentos indicam que o relevo japonês,  aliado com o vento, está favorecendo a elevação dos níveis de contaminação em  outras regiões.&lt;/span&gt;</content><link rel='replies' type='application/atom+xml' href='http://wiliampeninha.blogspot.com/feeds/6113227365399909287/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://wiliampeninha.blogspot.com/2011/06/toquio-ultimas-noticias.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/3371301833931668167/posts/default/6113227365399909287'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/3371301833931668167/posts/default/6113227365399909287'/><link rel='alternate' type='text/html' href='http://wiliampeninha.blogspot.com/2011/06/toquio-ultimas-noticias.html' title='Tóquio: ultimas notícias...'/><author><name>wiliam (==Peninha==)</name><uri>http://www.blogger.com/profile/09015219541019397908</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='29' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh2fSTAxoMxqzx7UdFRdCZa7fDAgYiZI2sBrQA9YPH74mTt0tmKitq9gdZIVrJLNZjFuDO5USYTZA5FMUaKdKuPCCepLr37us6pnXyEE5kqfYP_Tfs7rFRFGokwGs6ghQ/s220/Hacker_Teclando_Amarelo.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-3371301833931668167.post-663658869156423397</id><published>2011-06-10T11:44:00.000-03:00</published><updated>2011-06-10T11:44:23.625-03:00</updated><title type='text'>OMS anuncia que radiação de celular pode causar câncer</title><content type='html'>&amp;nbsp; As radiações emitidas por telefones celulares foram classificadas como &quot;possivelmente cancerígena para os seres humanos.&quot; pela&amp;nbsp;Organização Mundial de Saúde.A agência lista o uso do telefone móvel como&amp;nbsp;potencial causador de câncer, mesma categoria do chumbo, escapamento de motor de carro e clorofórmio.

&amp;nbsp; Uma equipe de 31 cientistas de 14 países, incluindo Estados Unidos, tomou a decisão depois de analisar estudos revisados por especialistas sobre a segurança de telefones celulares.&lt;br /&gt;
Isto significa que não existem estudos suficientes a longo prazo para concluir se a radiação dos telefones celulares é segura, mas há dados suficientes que mostram uma possível conexão, e que os consumidores devem ser alertados.</content><link rel='replies' type='application/atom+xml' href='http://wiliampeninha.blogspot.com/feeds/663658869156423397/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://wiliampeninha.blogspot.com/2011/06/oms-anuncia-que-radiacao-de-celular.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/3371301833931668167/posts/default/663658869156423397'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/3371301833931668167/posts/default/663658869156423397'/><link rel='alternate' type='text/html' href='http://wiliampeninha.blogspot.com/2011/06/oms-anuncia-que-radiacao-de-celular.html' title='OMS anuncia que radiação de celular pode causar câncer'/><author><name>wiliam (==Peninha==)</name><uri>http://www.blogger.com/profile/09015219541019397908</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='29' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh2fSTAxoMxqzx7UdFRdCZa7fDAgYiZI2sBrQA9YPH74mTt0tmKitq9gdZIVrJLNZjFuDO5USYTZA5FMUaKdKuPCCepLr37us6pnXyEE5kqfYP_Tfs7rFRFGokwGs6ghQ/s220/Hacker_Teclando_Amarelo.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-3371301833931668167.post-4062112716220223471</id><published>2011-06-01T16:13:00.001-03:00</published><updated>2011-06-01T16:15:43.054-03:00</updated><title type='text'>Partículas e ondas</title><content type='html'>&lt;span style=&quot;mso-bookmark: particulaseondas;&quot;&gt;&lt;/span&gt;&lt;span style=&quot;font-size: 14pt; mso-bidi-font-family: Arial; mso-bidi-font-size: 12.0pt;&quot;&gt;&amp;nbsp;&amp;nbsp; &lt;span style=&quot;font-size: small;&quot;&gt;A radiação pode ser de natureza particulada (de partículas) ou ondulatória (de ondas).&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;mso-bidi-font-family: Arial; mso-bidi-font-size: 12.0pt;&quot;&gt;&amp;nbsp;&amp;nbsp; A radiação de natureza particulada é caracterizada por sua carga, massa e velocidade: pode ser carregada ou neutra, leve ou pesada, lenta ou rápida. Prótons, nêutrons e elétrons ejetados de átomos ou núcleos atômicos são exemplos de radiação particulada.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;mso-bidi-font-family: Arial; mso-bidi-font-size: 12.0pt;&quot;&gt;&amp;nbsp;&amp;nbsp; A radiação eletromagnética é constituída por campos elétricos e magnéticos variando no espaço e no tempo. É caracterizada pela amplitude (tamanho) e pela freqüência (ou, alternativamente, pelo comprimento de onda) da oscilação.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;mso-bidi-font-family: Arial; mso-bidi-font-size: 12.0pt;&quot;&gt;&amp;nbsp;&amp;nbsp; A velocidade de propagação da radiação eletromagnética num dado meio é sempre constante, atingindo seu valor máximo no vácuo (cerca de 300.000 km/s). Apesar de não possuir carga ou massa, carrega energia e momento. A radiação eletromagnética é absorvida e emitida pela matéria em quanta (plural de quantum, palavra grega para &quot;pacote&quot;) de energia. As ondas de rádio, a luz visível e os raios-X são exemplos de radiação eletromagnética.&lt;/span&gt;&lt;br /&gt;

A ionização acontece quando a energia da radiação incidente sobre um material é suficiente para arrancar elétrons dos seus átomos. A radiação é dita não ionizante quando sua energia não é suficiente para arrancar elétrons dos átomos. Neste caso pode ocorrer a excitação do átomo, onde elétrons são levados a camadas mais externas do átomo, sem serem ejetados.&lt;br /&gt;
&lt;div style=&quot;border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;&quot;&gt;&amp;nbsp; Para a excitação de um átomo, a energia fornecida pela radiação deve ser igual à diferença de energia entre os níveis de origem e de destino do elétron.
