What does radiation do to us? Where does radiation come from?

Cullen The purpose of this post is to review how the preliminaries dose of ionizing radiation has reverted through geologic time until the present. I was motivated to write this by questions and misinformed statements made to me regarding the likelihood that the low levels of ionizing radiation now widow to the Pacific Ocean might harm marine microbes and powerfully skiver the wiring of the oceanic supplies uniting – given levels stuff measured this is for all intents and purposes impossible. This post is part of an ongoing series that summarizes the results of scientific research into the impact of the Fukushima Dai-ichi nuclear disaster on the health of the marine environment and residents of the west tailspin of North America. Life on Earth has been exposed to ionizing radiation since the first organisms began leaving chemical signs of their existence scrutinizingly 4 billion years ago. In a paper published in 1999 Karam and Leslie calculated how the dose experienced by organisms from naturally radioactive geological and biological materials has reverted over time. They find that overall the yearly beta and gamma dose experienced by organisms has dropped from well-nigh 7 millisievert (mSv = 0.001 Sv) 4 billion years ago to well-nigh 1.4 mSv today. Given the similarity of repair mechanisms that organisms use to cope with forfeiture from ionizing radiation it is likely that these mechanisms evolved early in Earth’s history which may explain why organisms are capable of dealing with higher than preliminaries doses in the environment today.

June 15, 2015 fukushimainform Leave a scuttlebutt By Jay T. Cullen Diatoms under the microscope. Important marine scum that form the wiring of the supplies web in oceanic environments. From http://www.nsf.gov/news/news_images.jsp?cntn_id=128913&org=NSF The purpose of this post is to write worldwide questions related to Fukushima monitoring efforts stuff conducted by the Integrated Fukushima Ocean Radionuclide Monitoring (InFORM) network in the northeast Pacific Ocean and coastal waters of Canada. This diary continues a series aimed to report the results of scientific research into the impact of the Fukushima disaster on the environment. I am asked routinely why we do not measure contamination in marine microalgae, the wiring of the marine foodweb, given that they concentrate radionuclide contamination from Fukushima found in seawater into their cells as they grow. The extremely low levels of contamination found from Fukushima in the northeast Pacific Ocean combined with the very small amounts of microalgae present in oceanic waters make such monitoring logistically infeasible. Follow unelevated the fold for the detailed answer.

Cullen Twitter follow @JayTCullen Map showing the location of public talks for the InFORM project June 1-4, 2015. The purpose of this post is to report on a recent public discussion tour to convey the latest results of the Integrated Fukushima Ocean Radionuclide Monitoring (InFORM) network to residents of the north tailspin of British Columbia. This post continues a series aimed to report the results of scientific research into the impact of the Fukushima disaster on the environment. Between June 1-4, 2015 I traveled from Victoria up to Haida Gwaii, over to Prince Rupert and up the Skeena River to Terrace and gave 8 public talks to communicate the results of the networks monitoring efforts to determine the impact of the Fukushima Dai-ichi meltdowns on the health of the northeast Pacific and residents of the North American west coast. I was worldly-wise to meet three of our resider scientist volunteers who have been collecting shoreline samples to squint for Fukushima derived contamination of coastal seawater. The response to these presentations was overwhelmingly positive and the public asked very useful questions well-nigh monitoring thus far. Despite the overall usefulness of the discussions some old misinformation keeps rearing its head. Here I’ll show some of the trappy spots on our tailspin and uncork the process of addressing some increasingly of the misinformation related to Fukushima impacts on the west coast.

April 20, 2015 fukushimainform 1ScuttlebuttBy Jay T. Cullen The purpose of this post is to introduce a brief, informal movie made while using a Geiger Counter in the laboratory today. This diary is part of an ongoing effort to communicate what the scientific polity is learning well-nigh the impact of the Fukushima disaster on environmental and public health. A Geiger Counter was used to examine ionizing radiation counts per minute in the laboratory owing to preliminaries radioactivity, the well-matured natural and man made isotopes in 20 liters of seawater placid by InFORM resider scientist volunteers, the uranium oxide glaze on a Fiestaware dinner platter and Uraninite ore mined from New Hampshire. This simple sit-in supports increasingly sensitive measurements indicating our resider scientists are exposed to no increasingly ionizing radiation than is typical of preliminaries when collecting seawater samples.
