Why Radiation Protection Makes Sense- even at ‘Low’ Exposure levels

Geiger CounterRadiation is all around us.

  It occurs naturally in our environment, coming to us from the sun, from the soil and foods that we eat, and in the air that we breathe. It is omnipresent across a diverse cross section of industries. We tend to associate radiation with the nuclear industry, but the reality is that we come across radiation sources in numerous other areas:  construction, health care, oil and gas, research, manufacturing, food processing – to name just a few.

With radiation being everywhere in our lives, it is not surprising that it garners a lot of attention, curiosity and, often, worry.

With more than 15 years as a career radiation protection professional, I’ve had to respond to many occupational radiation safety questions — some have related to regulations and compliance, others to potential health effects of exposure and ways to minimize such exposure. In all cases, it is best to rely on well established radiation physics concepts and scientific data, where available.

While there is not much that we can do to escape natural background radiation exposure, we do want to avoid any unnecessary exposure to high levels of radiation, such as the potential hazard due to elevated radon (a radioactive gas) in our homes and workplaces.

How to Protect Yourself From Harmful Mobile Cell Phone RF-EMF Radiation -  TurboFuture

Radon testing of homes is the simplest first step you can take to protect yourself and your family from radon gas, but all too often we do not make the time to educate ourselves and make this a priority. Workplaces are required to have a radiation protection program in place that is appropriate for the type of radiation and potential risk in their industry. But it takes time and investment to develop these programs, and it requires the commitment of both employers and workers to put these programs into practice.

Our challenge is that radiation and its associated risks are not always well understood.

On the one hand, we do not wish to alarm anyone unnecessarily, yet we want to make sure that the public, workers and employers are aware of the steps they need to take to stay safe.  Remember, we are talking about an “invisible” hazard that very rarely causes ill health effects in the short-term. Additionally, the existing radiation protection models are built on what we call the linear no-threshold concept, which, in simple terms, is based on studies of the atomic bomb survivors from the Second World War in Japan and other high-exposure situations, and extrapolates the information to the potential health effects of low exposures.

Low Levels Radiation

An agency of the World Health Organization (WHO) recently published a study on the health effects of low-level exposure to radiation that provides data to support the validity of the linear no-threshold model. We encourage all who read the study (available at The Lancet Haematology) to not get alarmed and to keep the study conclusions in perspective.

It suggests that extended exposure to low level of radiation increases the risk of developing leukemia.

A frightening statement, but we have to keep in mind that the increased risk is small, in line with what we have estimated based on the modeling concepts. This boils down to two things: first, it is important that we continue to apply the ALARA principle — “As Low as Reasonably Achievable” — to all our of interactions with radiation; and second, that we continue to view the numbers associated with radiation and risk in the proper context. The study points to a “small increase” of risk of dying from cancer from low levels of radiation exposure.

Let’s put this into perspective. 

If we extrapolate this study’s conclusions for nuclear workers to persons living near Canadian nuclear plants, people are 6,000 times more likely to die in a car accident, than to die from leukemia due to doses received from reactor plant emissions. Yet most of us think nothing of driving to work, driving our kids to school, or driving to visit friends and family.  The radiation risk is there, but it is significantly smaller than the risks we accept every day, often without even thinking or worrying about them.

More research is required on the health risks from low-level radiation exposure, and there are efforts underway around the world to make it happen. At the Radiation Safety Institute, we will be looking forward to hearing about more study results.  In the meantime we invite all people who are interested in the subject of radiation safety, who have a question or a concern, to reach out to our Free Information Service at 1-800-263-5803 or by e-mail at info@radiationsafety.ca. Let’s keep the conversation going.  For the Silo, Laura Boksman Chief Scientist at the Radiation Institute of Canada.

Art Of Painting With Camera Focus At Hurban Vortex Exhibit In Cannes

hurban-vortex-boris-wilenskyIf you could choose just one photo exhibit to see all year, it would have to be Hurban Vortex in Cannes.
Often, photography is the visual equivalent of telling a one-word story, expressed through an immediately comprehensible image. In contrast, Parisian photographer Boris Wilensky takes you on a journey through time, space, and humanity. His photos are true documentaries which require time to contemplate, and listen to. Yes, listen to, not just look at. Because all of his work tells a powerful, juxtaposing story. A story of humans in cruel, all-consuming urban environments… facing challenges beyond their control… surviving in harsh conditions… A story that is already written but that is reinvented every time you look at the image.

Boris Wilensky’s current exhibition Hurban Vortex at the Suquet des Art(iste)s in Cannes opened on December 9 last year, featuring a selection of 30 of his works. Much has been said and written about it, and him, since, so no further biographical introduction is needed. And what really shaped his life, are locations rather than dates – Israel and Palestine, Tokyo, Fukushima, and Cambodia.
An emotional trip to Israel and Palestine in 2005 left a big impression on the idealistic young man, and he started keeping and publishing travel journals to share his impressions. At some point he began illustrating those with photos. Meanwhile he kept working as a photographer in entertainment and sports.
In 2008, a café in Paris offered him space to display his photos. Thinking to himself, “This is a great opportunity… probably the only one I’ll ever have to exhibit”, he went for it. It was a success, and the impetus to turn his passion into a profession.

A visit to Tokyo in 2009 would prove to be the pathway into that professional career as an art photographer. The swirling, frenzied city of dazzling lights around the clock inspired him to find a way to capture the craziness of the megalopolis and the loneliness of its citizens … and he found a way to do so by superimposing two photos taken in the Tokyo subway, of the train and its travelers. It turned out so well that this type of photography would soon become his signature.

On his next visit to Japan – and in fact to Fukushima, just one month after the 2011 reactor catastrophe there – he found a country that had profoundly changed. The Japanese were beginning to awaken to the consequences of boundless, unchecked use of nuclear energy. As a consequence, the garish lights all over town were dimmed, and the mood had become much more somber and sober.

This was when the Hurban Vortex project started taking shape in the artist’s mind. “Hurban Vortex is an urban adventure with a big H”, he explains, the constant game between the concepts of humanity and urbanity, extending into notions of modernity and identity, future, sustainable development, ecology and economy. The City, symbolizing Progress and Modernity, in constant growth, now become a “megalopolis”, or a “City-world”, a space built by humans to live in but one that eats them up in return.

For this project, and forever drawn to Asia, Boris Wilensky returns to Tokyo, Shanghai and Bangkok to take as many “photographic backgrounds” as possible. Then he tours Cambodia for two months, the stark contrast to the other cities’ modernity. Here he immerses himself fully in the ancient Khmer culture, taking portraits of men, women and children. Many of those faces bear silent witness to the horrors of the Khmer Rouge regime, and yet retain pride and dignity that speaks of inner strength.

originsOver 15,000 photos later, Hurban Vortex sees the light of day. The ensemble of artistic, esthetic and human adventure are at the core of the triptych that represents his works: Origins corresponds to 2009 (present), the period of an oblivious, profligate, consumerism-driven world. Collapse takes us into 2011 (future)…Fukushima, with its worldwide impact. The glasses and gas masks worn by the humans represent the man-made destruction of a world as we had known it before and which will never be the same. And in Post we find ourselves in an urban landscape filled with waste and shattered ruins. But people are no longer wearing their blinders… Maybe there is hope after all that cities may disappear but humans are still around? Or does the urban jungle always win in the end? You decide, because it is your personal interpretation, after an intense dialogue with the image… exactly what Boris Wilensky wants.

origins2What the viewer sees, is how this artist sees the world – not in the literal but figurative sense. But he does not dictate, he suggests. He considers himself a storytelling portraitist first and foremost, and an urban photographer second. As you look at his large-size pictures (180 x 120 cm), the image in front of you transforms from a flat canvas to a three-dimensional scenography. You are drawn in, pulled onto a stage, you become part of the performance, an actor engaged in a dialogue. You are the person across from the man in the photo, but you also become him, turning outward to the viewer.

origins3The continuous movement – the vortex – pushes and pulls you as the borders between Human and Urban blur and become Hurban. There are violently cold and anonymous city landscapes, consisting of monochromatic and starkly geometric patterns, entirely unlike anything you find in nature. But the human element, superimposed, invariably bestows them with a strangely appealing aesthetic. For the Silo, Natja Igney. This article originates at Riviera-buzz.
