Teens and sunbed use; the regulation commences

Tuesday, October 6th, 2009

sunbed2The World Health Organisation’s (WHO) reclassification of sunbeds as carcinogenic has kick-started heated debate, with arguments from both sides making front page headlines around the world. Localised incidents are becoming catalysts for change, but the sad reality is that it’s often personal tragedies that serve to highlight the need for tighter regulation of the sunbed industry.

In Australia, the tragic case of Clare Oliver brought sunbed use and skin cancer risk to the top of the national agenda and as a result we now have one of the most tightly regulated industries in the world.

Light, UV and the electromagnetic spectrum

Wednesday, September 9th, 2009

spectrumSunlight is part of the electromagnetic spectrum, it’s  a form of radiation. The feature that characterises the different regions and classifications of radiation within the spectrum is the wavelength and wavelengths vary from being extremely long to measuring less than the width of a single atom.

Radiation from the sun consists of three types, or segments of the spectrum; infrared (IR), visible light and ultraviolet (UV), spanning wavelengths from 200nm to 2000nm. IR radiation is apparent in the heat and warmth we feel, its wavelengths are longer than those of visible light. The sense of vision and perceptions of colour are only possible due to the light radiation that can be detected by the human eye, visible light radiation.

Sunburn and skin cancer – a global problem that’s very local

Monday, August 24th, 2009

In Australia we have a highly developed respect for, and understanding of, the sun, light and UV radiation. Our location, environment and even national past times such as sports and swimming, ensure that we are rarely free from exposure to UV radiation and the risk of sunburn and skin damage.

This almost constant exposure to damaging radiation from the sun means that we have the highest incidence of skin cancer and melanoma in the world, with two out of three Australians likely to be diagnosed with some form it during their lifetime. A recent advertising campaign declared skin cancer to be ‘our national cancer’.

Sun-beds now known to cause cancer

Sun bed use linked to cancer

The International Agency for Research on Cancer (IARC) has upgraded the cancer risk factor for sun-beds to group 1, or ‘carcinogenic to humans’ based on research findings published in The Lancet Oncology medical journal. Previously sun-beds were considered group 2a, or ‘probably carcinogenic to humans’.

Another interesting finding is that sunbeds emitting UVA are now included in the category of increased carcinogenic risk. This revision places sunbeds as a primary risk factor for the development of skin cancer.
