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.

Hong Kong Board Predicts This New Post Covid Tourism Landscape

The Hong Kong Tourism Board (HKTB) hosted a web conference on April 24, 2020 to provide the latest updates on tourism development and introduce the HKTB’s strategic framework of recovery plan. HKTB Chairman Dr. YK Pang said that the Covid-19 pandemic has posed unprecedented challenges to Hong Kong tourism and put global tourism to a halt.

He continued, “The tourism landscape will be reshaped. In the post-pandemic world, we will see a shift in preference and behavior among travelers – the public health conditions of destinations, and the hygiene standards of transportation, hotels and other tourism facilities will become a top priority; people will prefer short-haul breaks and shorter itineraries; wellness-themed trips will become a new trend. It is an ideal time for us to review and rethink Hong Kong’s position in the global tourism market and elevate service standards. Together with the travel trade, the HKTB is going to map out the long-term development strategy for our tourism industry.”

The web conference was attended by close to 1,500 representatives from travel agencies, attractions, hotels, airlines, the retail and dining industries, as well as Meetings, Incentives, Conventions and Exhibitions (MICE) and cruise sectors. Representatives from the HKTB’s worldwide offices also participated in the meeting to provide insights into the latest developments in various market regions:

Mainland Market

  • The Mainland has gradually resumed economic activities and people have returned to work.
  • Given the outbreak’s impact on the economy, consumers will become more price-conscious and pursue value-for-money holidays. After prolonged confinement, visitors will also place greater emphasis on health and nature. When choosing destinations for future trips, they will favor those that pose low risks to health.
  • The Meeting and Incentive market has slowed down as many activities have been postponed or will be held online.

Short-haul and New Markets

  • Domestic travel will be the major preference shortly after the pandemic, and outbound travel will resume soon after.
  • Regional competition will be fiercer than ever, as the tourism authorities and travel trade of various destinations are gearing up for intensive promotions to vie for visitors.
  • In Japan, Korea and Taiwan, the young and middle-aged segments will be the most eager to travel. Green tourism and the outdoors will be favored, while short-haul travel will be preferred due to financial and holiday leave constraints.

Long-haul Markets

  • Currently, governments are focusing on containing the outbreak within the region. A longer time is expected for these markets to recover and outbound travel may resume in the last quarter of this year at the earliest.
  • Ethnic Asian visitors are expected to be the first to visit Hong Kong after the pandemic.
  • Consumer sentiment is comparatively more positive in Canada, France and Germany and outbound travel is expected to recover at a faster rate in these markets.

The HKTB has announced earlier that it will be allocating HK$400 million (US$51.2 million) to support promotions by the trade. HKTB Executive Director Dane Cheng explained that the HKTB has devised a three-phase plan to reinvigorate Hong Kong tourism. The exact timeline will depend on the development of the pandemic.

Phase 1 (Now) – Resilience

  • The HKTB is preparing a recovery plan for Hong Kong tourism.

Phase 2 – Recovery

  • When the pandemic shows signs of abating, the HKTB will first focus on local market to promote positive ambiance in Hong Kong by encouraging locals to rediscover different neighborhoods and community cultures in order to send a positive message to visitors and restore their confidence in the city. Meanwhile, the HKTB will launch tactical promotions with the trade in selected markets based on the developments of individual markets to stimulate people’s interest to visit Hong Kong.

Stage 3 – Relaunch

  • Mega events and a new tourism brand campaign will be launched to rebuild Hong Kong’s tourism image.

Professional salons respond to Canada’s “Teen tanban” legislation via JCTA

KELOWNA, B.C. – The Joint Canadian Tanning Association (JCTA) as the representative voice for Canada’s professional salon sector, responds to the Ontario government’s introduction of a “teen ban” on UV light exposure.

“Ontario’s  professional salon sector is disappointed that this legislation was brought forward. JCTA salons have long instituted standards which restrict access for youth, unfortunately due to the actions of a few bad apples within our industry who do not share the JCTA’s commitment to client protection, the government has felt the need to respond.” said Doug McNabb, JCTA President. http://tanresponsibly.ca/find-a-salon/

Professional salons, which comprise the JCTA’s membership, already mandate professional control over UV light exposure, age-based restrictions and the continuing education of salon workers. As a result, teenagers currently make up between 2 to 5% of salon sales. http://tanresponsibly.ca/professional-standards/

People who visit JCTA salons are by and large educated adults who look to patronize an establishment that cares as much about their health as they do- that’s why they don’t mind paying a few dollars more for top notch service. Additionally that is why teens have never been a significant market for us. All too often they refuse to take the long term steps needed to build a tan safely and as a result visit non-professional salons which do not limit exposure. Today we see the result of that.

Moving forward, the JCTA is eager to work with government to ensure that regulations under the act do not impose unnecessary red tape on small businesses, who continue to struggle in a difficult economic environment.

 “The JCTA is not opposed to the age based restriction – we currently have one in our professional standards. Our only concern at this point is to ensure that regulations under the act get it right and do not add unnecessary red tape to small businesses.” said Doug McNabb, JCTA President. Ontario’s indoor tanning sector currently comprises over 1000 small salons, operating in every corner of the province. Together these providers (mostly female operators) employ thousands of workers and generate millions of tax dollars for the province.

To Ontarians following this story all I can say is be smart about your choices. http://tanresponsibly.ca/ As an adult tanner you should only visit a professional salon – one that has a current JCTA sticker in the window – and never ever use a self-serve bed. Trained and industry certified operators controlling the equipment is one of the best ways for you to minimize risk.

This simplified diagram shows the spectrum of light. Tanning beds use UV ultra-violet light. At extreme frequencies, UV light can destroy cellular tissue-  the JCTA represents professional tanning salons in Canada and works to ensuring safety for all users. The recent move by the Canadian government to ban "teen tanning" is has upset the JCTA.

The Joint Canadian Tanning Association (JCTA) is a national non-profit organization created to increase understanding of the professional tanning industry’s scientifically supported position that regular moderate ultra-violet exposure from sunshine or sunbed in a non-burning fashion is part of a responsible lifestyle that recognizes both the inherent benefits and the manageable risks associated with ultraviolet light exposure.  For the Silo, Steven Gilroy Executive Director JCTA

Supplemental- It is difficult to contextualize the full story of tanning beds especially in terms of any possible associated health risks. Studies can show no health risk, little health risk, moderate health risk and severe health risk. These studies are greatly variable and depending on the subjects age, gender, health and tanning frequency and although the technology is the same for tanning salons, conditions and equipment can vary. The JCTA works towards ensuring safety standards are met by members. Check with your tanning salon to ensure that they are JCTA members in good standing.
