Amen. I'm not being insincer...No safe levels. Amen. I'm not being insincere. I am very risk averse, so I go to efforts to understand the risks.<br /><br />I'm not being sardonic. I canceled a recent dental cleaning here because the dentist refuses to forgo an annual x-ray.<br /><br />And an annual dental x-ray is usually not that much, if they have newer equipment.<br /><br />Look at this list, folks, and recognize your own significant radiation exposures. You are getting radiation. Knowledge is easy since it's been simplified by researchers into a very clear form. From the wiki on Sievert.<br /><br />Single (sudden) dose levels: <br /><br /> Dental radiography: 0.005 mSv[3]<br /> Average dose to people living within 16 km of Three Mile Island accident: 0.08 mSv during the accident[4]<br /> Mammogram: 3 mSv[3]<br /> Brain CT scan: 0.8–5 mSv[5]<br /> Chest CT scan: 6–18 mSv[5]<br /> Gastrointestinal series X-ray investigation: 14 mSv[6]<br /> International Commission on Radiological Protection recommended limit for volunteers averting major nuclear escalation: 500 mSv[7]<br /> International Commission on Radiological Protection recommended limit for volunteers rescuing lives or preventing serious injuries: 1000 mSv[7]<br /><br /><br />Now, some of your own inevitable dose levels: <br />Ongoing yearly accumulation dose levels:<br /><br />Dose from living near a nuclear power station: 0.0001–0.01 mSv/year[6][8]<br />Dose from living near a coal-fired power station: 0.0003 mSv/year[8]<br />Dose from sleeping next to a human for 8 hours every night: 0.02 mSv/yr[8]<br />Dose from Cosmic radiation (from sky) at sea level: 0.24 mSv/year[6]<br />Dose from Terrestrial radiation (from ground): 0.28 mSv/year[6]<br />Dose from Natural radiation in the human body: 0.40 mSv/year[6]<br />Dose from standing in front of the granite of the United States Capitol building: 0.85 mSv/year[14]<br />Average individual background radiation dose: 2 mSv/year; 1.5 mSv/year for Australians, 3.0 mSv/year for Americans[8][4][9]<br />Dose from atmospheric sources (mostly radon): 2 mSv/year[6][15]<br />Total average radiation dose for Americans: 6.2 mSv/year[16]<br />New York-Tokyo flights for airline crew: 9 mSv/year[9]<br />Dose from smoking 30 cigarettes a day Smoking: 13-60 mSv/year[14][15]<br />Current average dose limit for nuclear workers: 20 mSv/year[9]<br />Dose from background radiation in parts of Iran, India and Europe: 50 mSv/year[9]<br />Dose limit applied to workers during Fukushima emergency: 250 mSv/year[17]<br /><br /><br />American background cancer rate: your odds of death by cancer currently at about 42/100, or 42%.Hal Horvathhttps://www.blogger.com/profile/10851897967853698214noreply@blogger.comtag:blogger.com,1999:blog-53246864840716464.post-26413238255290524182011-04-08T09:18:30.078-07:002011-04-08T09:18:30.078-07:00What amazes me is that citizens in the US still in...What amazes me is that citizens in the US still insist on believing their government.easyplankinhttps://www.blogger.com/profile/15341768486833105435noreply@blogger.comtag:blogger.com,1999:blog-53246864840716464.post-91649289467598165962011-04-08T08:23:14.845-07:002011-04-08T08:23:14.845-07:00There may not be a "safe" level of radia...There may not be a "safe" level of radiation exposure, but since natural radiation exposure varies from place to place, surely additional radiation that's only a fraction of natural exposure is no cause for concern.quadiblochttps://www.blogger.com/profile/02677796062022258684noreply@blogger.comtag:blogger.com,1999:blog-53246864840716464.post-89886594258666911242011-04-08T01:31:18.128-07:002011-04-08T01:31:18.128-07:00Don't "HARP" on that comment!
