The use of compact fluorescent lamps for general lighting
purposes in households is of no concern from a radiation protection point of
view. Present studies demonstrate, that the levels of emitted optical radiation
and electric and magnetic fields comply with internationally recommended limit
values.
Several characteristics of compact fluorescent lamps, which are
important for risk assessment, differ only slightly from those of incandescent
lamps. When staring straight into a light source for a sufficient period of
time, the inherent blue light fraction of incandescent lamps can result in a
higher risk for the eye than that of compact fluorescent lamps. Furthermore,
the technology of compact fluorescent lamps is very similar to that of the widespread
fluorescent tubes.
Proven measure in radiation protection: reduction of avoidable exposures
In addition to the requirement to comply with the respective limit values, the reduction of avoidable exposures is a proven measure in radiation protection. The reduction of avoidable exposures even below limits as a precautionary measure is based on the following aspects:
- UV radiation is classified as a carcinogen;
- already weak UV radiation can cause adverse health effects;
- the knowledge about possible health risks from electric and magnetic fields with frequencies in the kilohertz range is limited compared to other areas of the electromagnetic spectrum, including risks associated with UV radiation. Therefore, there are additional uncertainties in the health assessment with respect to these frequencies.
As a consequence lamps for domestic use should emit only low levels of electromagnetic radiation outside the visible range.
Although internationally recommended limit values are being complied
with, differences occurThe measurements carried out by the BfS and the few data published by others show that major differences exist in the market for compact fluorescent lamps between different brands.
BfS therefore calls upon the manufacturers to introduce an easily recognizable label of those lamps, which among others meet aspects of precautionary radiation protection. The "Blue Angel" (RAL-UZ 151) is an example of such a label.
