Fukushima radiation reaches Canadian waters Radiation from Japan’s leaking Fukushima nuclear power plant has reached ocean waters offshore Canada, researchers said on February 24. Since the 2011 Fukushima accident, researchers from the Bedford Institute of Oceanography have been sampling waters along a line running almost 2,000km due west of Vancouver, British Columbia. www.bbc.com/news/science-environment-26329323

What this has generated is, from 2004 up to this day, we are seeing a rate of congenital malformations in the city of Fallujah that has surpassed even that in the wake of the Japanese cities of Hiroshima and Nagasaki that nuclear bombs were dropped on at the end of World War II." Jamail has also reported on the refugee crisis of more than one million displaced Iraqis still inside the country, who are struggling to survive without government aid, a majority of them living in Baghdad. www.democracynow.org/2013/3/20/ten_years_later_us_has_leftRecommended Maximum Permissible Dose Equivalent Limits for Ionizing Radiation (Safety Requirements And Guidance For Analytical X-ray Equipment - Safety Code 32) For women who are or may be pregnant, the fetus must be protected from radiation exposure once pregnancy has been diagnosed. For the remainder of the pregnancy, the dose equivalent limit from radiation sources external to the body is 2 mSv applied to the surface of the abdomen, and the limit for radionuclides taken internally by the body is 1/20th of the allowable annual intake. If a woman is exposed to both internal and external sources, both limits apply separately and the total limit shall not exceed 1 mSv (since the fetus is considered a member of the public). www.hc-sc.gc.ca/ewh-semt/pubs/radiation/94ehd-dhm186/index-eng.php__________________________________ Pregnancy and Radiation Exposure Another important consideration is the stage of pregnancy in which the radiation exposure occurred: - In the first two weeks postconception or the second two weeks from the last menstrual period, the embryo is very resistant to the malforming effects of x rays. The embryo is, however, sensitive to the lethal effects of x rays, although doses much higher than 50 mSv are necessary to cause a miscarriage.
- From the third to the eighth week of pregnancy, the embryo is in the period of early embryonic development but is not affected with either birth defects, pregnancy loss, or growth retardation unless the exposure is substantially above the 200 mSv exposure.
- From the eighth to the fifteenth week of pregnancy, the embryo or fetus is sensitive to the effects of radiation on the central nervous system. But here again, the exposure has to be very high. The threshold has been estimated to be higher than 300 mSv before an effect can be seen on the IQ of the developing embryo. General diagnostic studies do not reach these levels and, therefore, these effects are rarely of concern for patients.
- Beyond the 20th week of pregnancy, when the fetus is completely developed, it has become more resistant to the developmental effects of radiation. In fact, the fetus is probably no more vulnerable to many of the effects of radiation than the mother in the latter part of pregnancy. But the most important thing is that practically none of the diagnostic radiological procedures will affect an embryo at this late stage of pregnancy and certainly there is no risk for birth defects or miscarriage from the range of exposures that occur from diagnostic studies.
- The reproductive risk of nonionizing radiation, which includes electromagnetic fields emitted from computers, microwave communication systems, microwave ovens, power lines, cellular phones, household appliances, heating pads and warming blankets, airport screening devices for metal objects, and diagnostic levels of ultrasound, has been studied extensively. Two national committees of scientists evaluated the risk from these nonionizing radiation sources. Both of the committees published books on the subject. The first came out in 1993 from the Oak Ridge Associated University panel created by the White House while the second was the product of the committee of the National Academy of Sciences. Both of these groups concluded that the reproductive risk of nonionizing radiation is minimal if even existent.

Nuclear safety watchdog head fired for 'lack of leadership': minister CBC News Posted: Jan 16, 2008 5:29 AM ET Last Updated: Jan 16, 2008 5:26 AM ET A ministerial directive [Federal Natural Resources Minister Gary Lunn] on Dec. 10 ordered the CNSC to reopen the site. The agency refused, insisting a backup safety system be installed to prevent the risk of a meltdown during an earthquake or other disaster. On Dec. 11, an emergency measure passed through the House of Commons overturned the watchdog's decision, and the reactor was restarted for a 120-day run on Dec. 16. more: www.cbc.ca/news/canada/nuclear-safety-watchdog-head-fired-for-lack-of-leadership-minister-1.7488153.5-magnitude quake near Ontario nuclear facility | Mar 29, 2011 5.2-magnitude quake in the Shawville, Quebec region and was felt in Chalk River | May 17, 2013 ...

Emergency crews rushed to Nordion’s March Road headquarters just before 10:30 a.m. Thursday after a fire broke out during roof repairs. Nordion processes nuclear substances (radioisotopes) for medical and industrial applications. It is licensed by the Canadian Nuclear Safety Commission to operate a nuclear substance processing facility. more: ottawacitizen.com/news/local-news/crews-fight-fire-on-roof-at-nordion-inc-offices_________________________ Treaty on the Non-Proliferation of Nuclear Weapons non-parties: India, Israel, North Korea, Pakistan and South Sudan
