Strontium-90
EPA Facts about Strontium-90 What is strontium-90? The most common isotope of strontium is strontium-90. Radioactive strontium-90 is produced when uranium and plutonium undergo fission. Fission The time required for a radioactive substance to is the process in which the nucleus of a lose 50 percent of its radioactivity by decay is radionuclide breaks into smaller parts. Large known as the half-life. Strontium-90 has a half- amounts of radioactive strontium-90 were life of 29 years and emits beta particles of produced during atmospheric nuclear weapons relatively low energy as it decays. Yttrium-90, its tests conducted in the 1950s and 1960s. As a decay product, has a shorter half-life (64 hours) result of atmospheric testing and radioactive than strontium-90, but it emits beta particles of fallout, this strontium was dispersed and higher energy. deposited on the earth.

``Low Dose``And/Or``High Dose``In Radiation Protection: a Need To
IAEA-CN-67/154 "LOW DOSE" AND/OR "HIGH DOSE" IN RADIATION PROTECTION: A NEED TO SETTING CRITERIA FOR DOSE CLASSIFICATION Mehdi Sohrabi National Radiation Protection Department & XA9745670 Center for Research on Elevated Natural Radiation Atomic Energy Organization of Iran, Tehran ABSTRACT The "low dose" and/or "high dose" of ionizing radiation are common terms widely used in radiation applications, radiation protection and radiobiology, and natural radiation environment. Reading the title, the papers of this interesting and highly important conference and the related literature, one can simply raise the question; "What are the levels and/or criteria for defining a low dose or a high dose of ionizing radiation?". This is due to the fact that the criteria for these terms and for dose levels between these two extreme quantities have not yet been set, so that the terms relatively lower doses or higher doses are usually applied. Therefore, setting criteria for classification of radiation doses in the above mentioned areas seems a vital need. The author while realizing the existing problems to achieve this important task, has made efforts in this paper to justify this need and has proposed some criteria, in particular for the classification of natural radiation areas, based on a system of dose limitation. In radiation applications, a "low dose" is commonly associated to applications delivering a dose such as given to a patient in a medical diagnosis and a "high dose" is referred to a dose in applications such as radiotherapy, mutation breeding, control of sprouting, control of insects, delay ripening, and sterilization having a range of doses from 1 to 105 Gy, for which the term "high dose dosimetry" is applied [1]. -
Introduction
/ Introduction Aft er the 1986 nuclear disaster in Chernobyl, the name of this Ukrainian town became synonymous with the worst accident ever to have occurred in the civil use of nuclear energy. Chernobyl has retained this status ever since, that is, until 11 March 2011, when an earthquake and the resulting tsunami partially destroyed the Japanese nuclear power plant at Fukushima. Th e meltdown of the core at Chernobyl, classifi ed as category 7 on the International Nuclear and Radiological Event Scale, was indeed considered the worst accident that could happen at a nuclear power plant. Technically, the actual meltdown is over. Chernobyl is seen as an event of the past, to which a start and an end were attributed by the technical evaluations following the evolution of the in- cident. However, its consequences are far from over. As with war, the scars of a nuclear catastrophe run deep; the aft ermath is engraved in the environment, in people’s bodies and in their memories. Signing a peace treaty does not bring an end to suff ering; burying a destroyed reactor core under tons of concrete does not mean the evacuees can come home and simply forget what happened. Comparing the Chernobyl disaster to a war scene is not just the result of a creative thinking process too strongly conditioned by my research. Many Ukrainian and Belarusian accounts narrate and interpret the struggle en- dured by fi refi ghters and rescue workers as a battle against an enemy: the burning reactor. Th e victims, destruction and displacements provoked by this burning reactor have been linked to those caused by the Second World War. -

Life on our planet as we know it is dying from fossil fuel pollution and the related global warming and ocean acidification. We need as much clean CO2 free energy generation as we can get and we need it as soon as we can get it. For supporting documentation see George Erickson's book Unintended Consequences. I fully agree with his comment and attachments related to this proposed rule. I have attached a pdf copy of his book.

Oakley1 and Deed E. Harrison2 Abstract There are pressures to avoid use of radiological imaging throughout all healthcare due to the notion that all radiation is carci- nogenic. This perception stems from the long-standing use of the linear no-threshold (LNT) assumption of risk associated with radiation exposures. This societal perception has led to relentless efforts to avoid and reduce radiation exposures to patients at great costs. Many radiation reduction campaigns have been launched to dissuade doctors from using radiation imaging. Lower- dose imaging techniques and practices are being advocated. Alternate imaging procedures are encouraged. Are these efforts warranted? Based on recent evidence, LNT ideology is shown to be defunct for risk assessment at low-dose exposure ranges which includes X-rays and CT scans. -
Radiation and Health
Radiation and Health by Thormod Henriksen and Biophysics group at UiO Preface The present book is an update and extension of three previous books from groups of scientists at the University of Oslo. The books are: I. Radioaktivitet – Stråling – Helse Written by; Thormod Henriksen, Finn Ingebretsen, Anders Storruste and Erling Stranden. Universitetsforlaget AS 1987 ISBN 82-00-03339-2 I would like to thank my coauthors for all discussions and for all the data used in this book. The book was released only a few months after the Chernobyl accident. II. Stråling og Helse Written by Thormod Henriksen, Finn Ingebretsen, Anders Storruste, Terje Strand, Tove Svendby and Per Wethe. Institute of Physics, University of Oslo 1993 and 1995 ISBN 82-992073-2-0 This book was an update of the book above. It has been used in several courses at The University of Oslo. Furthermore, the book was again up- dated in 1998 and published on the Internet. The address is: www.afl.hitos.no/mfysikk/rad/straling_innh.htm III. Radiation and Health Written by Thormod Henriksen and H. David Maillie Taylor & Francis 2003 ISBN 0-415-27162-2 This English written book was mainly a translation from the books above. I would like to take this opportunity to thank David for all help with the translation. The three books concentrated to a large extent on the basic properties of ionizing radiation. Efforts were made to describe the background ra- diation as well as the release of radioactivity from reactor accidents and fallout from nuclear explosions in the atmosphere. These subjects were of high interest in the aftermath of the Chernobyl accident. -

Mockensturm: Radiophobia and Trauma Mockensturm 1 Radiophobia and Trauma: Examining the Lasting Effects of the Fukushima Nuclear Disaster Lydiarose Mockensturm The Fukushima nuclear disaster of March 2011, unlike the earthquake and tsunami leading up to it, was not experienced directly or immediately for many. Its effects were, however, experienced belatedly–in the form of displacement and radiophobia, which have had a significant psychological impact on survivors. Moreover, excessive media coverage of the disaster allowed for it to have a global impact not seen during previous nuclear disasters. Shion Sono’s film The Land of Hope, released in Japan in October of 2012, helps to illustrate the traumatic nature of a nuclear crisis through issues such as dislocation, media coverage, radiophobia, and distrust of the government. The Fukushima Daiichi nuclear disaster in March 2011 and the earthquake and tsunami that led up to it have thus far made up the most devastating event in Japan since the atomic bombing of Hiroshima and Nagasaki during World War II (Osawa 189).
