But, what if a short-term controlled exposure to a low dose of radiation were good for our health. Writing in today's issue of the Inderscience publication the International Journal of Low Radiation, Don Luckey, makes the startling claim that low dose radiation could be just what the doctor ordered!
Luckey, an emeritus professor of the University of Missouri, was the nutrition consultant for NASA's Apollo 11 to 17 moon missions and has spent the last several years developing the concept of improving health through exposure to low-dose radiation.
"When beliefs are abandoned and evidence from only whole body exposures to mammals is considered, it becomes obvious that increased ionising radiation would provide abundant health," Luckey explains. He suggests that as with many nutritional elements, such as vitamins and trace metals it is possible to become deficient in radiation. "A radiation deficiency is seen in a variety of species, including rats and mice; the evidence for a radiation deficiency in humans is compelling."
In the first part of the twentieth century at a time when our understanding of radioactivity was only just emerging, health practitioners began to experiment widely with samples of radioactive materials. Then, exposure to radiation, rather than being seen as hazardous, was considered a panacea for a wide variety of ailments from arthritis to consumption.
The discovery of antibiotics and the rapid advent of the pharmaceutical industry, as well as the fact that it became apparent that exposure to high doses of radiation could be lethal led to the demise of this "alternative" approach to health.
Today, radioactivity is used in targeted therapies for certain forms of cancer, however, the use of radiation sources for treating other diseases is not currently recognised by the medical profession.
Luckey hopes to change that viewpoint and argues that more than 3000 scientific papers in the research literature point to low doses of radiation as being beneficial in human health. He points out that, as with many environmental factors, we have evolved to live successfully in the presence of ionising radiations. His own research suggests that radiation exposure can minimise infectious disease, reduce the incidence of cancer in the young, and substantially increase average lifespan.
Studies on the growth, average lifespan, and decreased cancer mortality rates of humans exposed to low-dose irradiation show improved health, explains Luckey. This represents good evidence that we live with a partial radiation deficiency and that greater exposure to radiation would improve our health, a notion supported by 130 on the health of people living in parts of the world with higher background levels of ionising radiation than average.
Luckey suggests that the medical use of small samples of partially shielded radioactive waste would provide a simple solution to radiation deficiency. Of course, there are several questions that will have to be answered before a health program based on this study could be implemented. How much should we have and what is the optimum exposure?
Evidence suggests that low dose exposure increases the number and activity of the immune system's white blood cells, boosts cytocrine and enzyme activity, and increases antibody production and so reduces the incidence of infection, assists in wound healing, and protects us from exposure to high doses of radiation.
"It is unfortunate that most literature of radiobiology involves fear and regulations about the minimum possible exposure with no regard for radiation as a beneficial agent," says Luckey, "Those who believe the Linear No Threshold (LNT) dogma have no concept about any benefits from ionising radiation. Many radiobiologists get paid to protect us from negligible amounts of ionising radiation. Our major concern is health."
Professor André Maïsseu, the journal's Editor-in-Chief, and President of the World Council of Nuclear Workers WONUC) says: "This is a very bright, interesting and important paper about the real effects of ionising radiation - radioactivity - on humans, mammals and biotopes." He adds that, the paper, "is part of the movement we - nuclear workers - promoting good science and fighting obscurantism in this scientific field.
Maïsseu points out that the European Union recently refused to support a world-wide study on related work. "This was the first time nuclear workers have asked the European Union to support a scientific study," Maïsseu says, "We received nothing yet for more than thirty years, so-called 'green' organisations have received hundreds of millions euros, and with what results?" He adds that, "It is a shame and a scandal that political reasons are being used to decide on science funding."

A Challenging European Research Project to Develop New Tiny Microscopes
28.03.2017 | Technische Universität Braunschweig
The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
