Dangers of Ultra Violet Rays in Fluorescent Light Bulbs

Concerns about ultraviolet radiation have plagued fluorescent technology for quite some time, and while the majority of people have little reason to worry, the available information can be complex and difficult to understand. Given the significant energy savings these bulbs offer, it's important to get the facts straight so consumers can make informed decisions.

Cause for Concern

• "The Lancet" published a study in 1982 discussing a possible link between malignant melanoma and fluorescent office lighting. The study concluded that the connection was "plausible" but should be "viewed cautiously" until more information could be gathered.

Recent Studies

• Since 1982, various independent and government organizations such as the European Commission Scientific Committee on Emerging and Newly Identified Health Risks and the Australian Radiation Protection and Nuclear Safety Agency have conducted studies that found that the ultraviolet rays emitted by fluorescents are not strong enough to cause skin cancer.

How Much UV?

• The ARPANSA studies found that it would take six hours of exposure at a distance of 10 cm (4 inches) from a compact fluorescent bulb for exposure limits to equal that of approximately six minutes in midday sunlight.

Who is at Risk?

• Fluorescent bulbs do give off some ultraviolet radiation, and as such can be a concern for people with exceptionally sensitive skin conditions. However, this is an extremely small portion of the population.

Conclusion

• For the vast majority of the population, ultraviolet rays from fluorescents should not cause any health issues. In most cases, individuals with rare skin conditions can safely use "double envelope" compact fluorescent light bulbs which emit little to no ultraviolet rays.
