Optical radiation is ubiquitous, and intense artificial sources find many applications in clinical practice, including zone illumination, diagnosis, and therapy. Its effects on humans are strongly wavelength-dependent, its hazards sometimes overlooked due to familiarity or masking by other wavelengths. This chapter examines non-laser sources of ultraviolet, visible, and infrared radiations, the risks likely to be encountered in clinical settings, the calculations needed to assess commonly encountered optical radiation sources, and the measures that can be taken to minimize the hazards to workers and patients, in compliance with the requirements of the Artificial Optical Radiation directive.

Wax Moth

The authors found out that the greater wax moth (Galleria mellonella) harmed bee colonies by destroying up to 30 percent of honey in a beehive. They studied the results of experiments on controlling its behavior using a developed automated microprocessor system that maintained optical radiation sources duration.(Research purpose) To develop light technologies using a microprocessor-based automated system that allows controlling Galleria mellonella behavior by realizing attractive optical radiation characteristics.(Materials and methods) Galleria mellonella behavior was controlled by an automated system that the authors worked out for maintaining the required duration of the experiment and optical radiation parameters. The ATmega328 microcontroller was chosen as the main element of the developed microprocessor automated system. The authors created a program for it using visual programming FLProg version 5.3.0.(Results and discussion) The authors found that, regardless of the experiment duration, Galleria mellonella butterflies prefered radiation with 400 nanometers wavelength.(Conclusions) The authors determined that radiation with 400 nanometers wavelength and 10 minutes duration was attractive. They showed the ability to control Galleria mellonella behavior, luring butterflies to a specific place in the beehive with comfortable spectrum parameters. An automated system for controlling the greater wax moth butterfly behavior was developed on ATmega328 microcontroller by implementing attractive optical radiation characteristics.

Abstract This article gives an insight into the theory and application of photobiological safety assessment. To illustrate several aspects of this topic, the project ‘Measurement and assessment of optical radiation sources, relevant to the general population – Risk estimation to the eye, especially blue light hazard and glare’ by the German Federal Office for Radiation Protection, where 40 different products were measured and assessed, is used as an exemplary case. Products were chosen which were promoted to have a high output intensity and which are available to the public. Most of the products with incoherent radiation were classified in risk group 2 according to DIN EN 62471:2009 [DIN EN 62471:2009 – ‘Photobiologische Sicherheit von Lampen und Lampensystemen’]. Only a few of them were labeled correctly or had the right warning notice. Additionally, to the results of this market survey, practical aspects of the hazard measurement and assessment are emphasized.
