radiation from uvc surfaces

What requirements must UVC disinfection devices meet for their safe and effective use?

UV-C technology has proven its effectiveness for disinfection of the environment and surfaces, being able to inactivate viruses, bacteria, spores, protozoa and other microorganisms with a high disinfection rate. However, type C ultraviolet radiation is harmful to living beings so all devices must follow some guidelines so that their use is completely safe and effective.

In Spain and following the European guidelines and indications, the use of devices for UV disinfection such as germicidal lamps or air disinfection equipment, are regulated by UNE0068. This regulation has been created due to the popularization of technology during the pandemic, given its effectiveness against other ineffective and unsafe options such as Ozone.


In addition to specifying aspects of its electronic components, materials, labeling and information, it determines some key points that the equipment must have so that its use is safe:

  • UV-C radiation devices cannot be used with living beings exposed to radiationTherefore, they must contain security sensors to avoid this, such as presence sensors and a timer. In the case of the Goldensea UV devices used by Stonex, they have motion and presence sensors, timer and delayed start, as well as other additional measures such as alarm, security locks and tilt.
  • The security measures of the space must be guaranteed and verify that the specifications are met. For this reason, Stonex offers a 360 solution, in which the engineering team analyzes the needs of the space and the installation and verification is carried out by specialized personnel.
  • The end user of the devices must receive training on their use and the different dangers and precautions you have to take. Stonex for its part offers training on equipment, easy to understand and internalize for all your staff.

What should we take into account in air disinfection equipment?

Teams uvc air disinfection They have the advantage of working by indirect radiation, since it affects the air and not the surfaces and therefore living beings. These devices can be used in the presence of people safely, but it is necessary that we make sure that they do not emit external radiation outside the equipment, which can affect living beings.

The UV AIR devices used by Stonex have been validated through studies of non-emission of external radiation by the laboratory of the University of Hamburg and the Spanish company CandelTEC, thus certifying that its use is totally safe with living beings in the space that is being disinfected.

One of the key points to take into account when analyzing the effectiveness of disinfection of the environment is the flow of air that it is capable of disinfecting and the cycles per hour in which it renews the air, especially in large spaces. For example, UV AIR devices are capable of moving large amounts of air with a reduction rate greater than 99,93%.

Air flow is a key point to analyze, since, for example, the effectiveness of purifiers decreases by basing its effectiveness on dense Hepa filters that slow the air, unlike UV-C disinfection equipment that does not need them. This air brake prevents the environment from being renewed more frequently, one of the essential requirements for infection prevention.

Using the right equipment for each space is an essential element to guarantee the effectiveness of the devices, both surfaces, air or objects. Each space is unique and needs a different radiation, so in addition to the physical equipment, professional assistance will help you choose the most effective option.

Stonex has dosimeters that allow measuring the radiation to which a surface is being exposed, to check that disinfection is being carried out effectively in every place where UV disinfection equipment is used.
