Where radiello is used…

The versatility of radiello and its ease of use allow to measure the concentration levels of airborne pollutants in the main situations of hygienic-industrial and environmental interest.

radiello, in particular, is suitable for assessing the risk of occupational exposure to chemical agents (industrial hygiene), monitoring urban air quality (environmental hygiene) and studying air quality in environments such as homes and offices (Indoor Air Quality).

Numerous examples of radiello applications are available in the scientific literature section.


radiello is a particularly effective instrument, in compliance with the requirements of the UNI EN 838 standard, both for the measurement of personal exposure and in fixed positions.
In the determination of personal exposure by inhalation to chemical agents, worn by operators, is able to take the chemical risk agents airborne in the respiratory zone and to follow the operators in all their movements. Because of its weight and size, it can be easily worn by the worker without hindering him and therefore without changing his activity.
The quietness of the radiello makes it particularly suitable for carrying out measurements in work environments such as offices, schools, hospitals, etc. without disturbing the concentration of the operators.
The fact that it does not require any type of power supply and does not generate electrostatic discharges allows it to be used in environments at risk of explosion, such as refineries, chemical industries, silos, confined areas, etc..

When used in fixed or area positions, it allows to characterize the extent of suspected sources of pollution in areas frequented by employees for the purposes of interventions of a plant engineering and/or organizational nature that may be necessary for the prevention of exposure risk.

Thanks to the sensitivity of the method that can be achieved, radiello allows comparison with the most restrictive limits. With radiello it is therefore possible to assess the risk of occupational exposure of workers to various chemical agents both during the entire work shift (typically 8 hours) and over a short period (15 minutes).
Radiello allows to compare exposures, for individual workers or for Similar Exposure Groups (SEG), with the limit values provided by the Legislative Decree 81/2008 or with the Threshold Limit Values (OELV) proposed by international organizations such as, for example, the Scientific Committee on Exposure Level (SCOEL/RAC) of the European Community, the TLV-TWA or the STEL/C proposed by the American Conference of Governmental Industrial Hygienists (ACGIH), the OSHA PELs of the Occupational Safety and Health Administration, the NIOSH RELs of the National Institute for Occupational Safety and Health or the DFG MAKs of the Deutsche Forschungsgemeinschaft.

Radiello meets the technical requirements of the equipment (sampling pumps, diffusion pipes, short-term measuring systems, absorption pipes, sampling pumps with flow rates greater than 5 l-min-1) defined by the standard UNI EN 482 – Atmosphere in the workplace. General requirements for the performance of chemical measurement procedures and, due to its low cost, makes risk assessment according to the criteria laid down in UNI EN 689 – Occupational exposure – Measurement of inhalation exposure to chemical agents – Strategy for verifying compliance with occupational exposure limit values.

ENVIRONMENTAL HYGIENE – Living environments

Radiello is a simple and economical tool, able to offer a solution to a widespread problem: the production of environmental data that are representative of the real situation. radiello is able to guarantee limits of analytical sensitivity compatible with the ordinary levels of urban air pollution and industrialized areas, producing precise and accurate results.

To expose radiello to the outside, it is available a sectional shelter in polypropylene (Insert photo protective box), to hang to the poles of the light. The shelter is constructed in such a way as not to occupy space in transport and to be assembled in the field quickly without the need for any tools. Once assembled, it ensures the best compromise between shelter efficiency and ventilation.

Scientifically known sources of environmental pollution are those deriving from combustion processes (vehicle traffic, domestic heating, incinerators, etc.), or from specific industrial or production processes. In this context, the contribution deriving from natural sources must not be neglected. Among the main air pollutants in urban environments are generally considered gases and vapours such as sulphur dioxide (SO2), nitrogen oxides (NOx), ozone (O3), aromatic compounds (BTEX) and volatile organic compounds (VOC).

Verification of compliance with the concentration limits of airborne pollutants is based on the availability of qualitatively reliable environmental data. The problem has a multifaceted aspect: on the one hand, the protection of the health of the population, on the other hand, the correctness of spatial planning. The low cost of radiello sampling allows the execution of measurement campaigns of environmental pollution levels with high spatial resolution, allowing the simultaneous collection of environmental data from a large number of measurement positions. The availability of a large number of environmental data, distributed on a reasoned grid, allows the drawing up of concentration island-level maps, which, through an overall view of the spatial distribution of pollutants, allow the verification of forecast models and help to locate both diffuse and point sources.


Thanks to its silence and its small size radiello is particularly suitable for monitoring pollutants in confined environments (indoor), not requiring difficult and cumbersome installations or generating noises that could disturb the quiet home or concentration during work activities.
Indoor Air Quality refers to the air you breathe in confined non-industrial (offices, hospitals, schools, etc.), residential or recreational (shops, cinemas, restaurants, etc.) work environments.

The sources of pollution are mainly furniture and furnishings, paints, cigarette smoke, household hygiene products, food preparation and air that can come from outside.
The most frequent chemical agents are carbon monoxide and dioxide, sulphur and nitrogen oxides, ozone (emitted for example by photocopiers), volatile organic compounds, aldehydes.
At the international level, many countries have already introduced standards for indoor pollutants into their legislation; this has also contributed to the implementation of indoor air quality monitoring campaigns as part of special programmes.
The World Health Organization (WHO) has drawn up European guidelines for indoor air quality (WHO Guidelines for Indoor Air Quality: Selected Pollutants) for certain specific air pollutants present in confined environments.
At European level, the “Guidelines for health-based ventilation in Europe” have been proposed, which require that human exposure to indoor pollutants be controlled through a sequential approach in which the identification and control of pollutant sources is the main strategy, while ventilation is the secondary strategy. WHO air quality guidelines (AQ) are used to set exposure limits.
In the US, many states have introduced a Green Building Tax Credit to encourage owners and tenants of buildings that meet certain “green” standards. These standards increase energy efficiency, improve indoor air quality and reduce environmental impacts.
The concept of green building is becoming more and more popular worldwide, indicating a way of designing, constructing and managing a building in line with the principles of environmental sustainability, improving the comfort of living or working there and protecting the health of the building thanks to good levels of indoor air quality.
radiello offers a valid and non-invasive system for the identification and monitoring over time of the main indoor pollutants.
