There have been several concerns about the environmental persistence of SARS-CoV-2 virus. These concerns led to the formulation of sanitation measures that try to lower the risk of indirect transmission of SARS-CoV-2 in non-medical facilities. This manuscript will elucidate the topic of environmental persistence of SARS-CoV-2. This will benefit the occupational health professionals two-fold. It describes the proper techniques for an effective sanitation of the workplace. It also explains how to protect workers who are responsible for carrying out these interventions.

Occupational solar radiation exposure is a relevant heath risk in the fishing sector. Our aim was to provide a detailed evaluation of individual UV exposure in three different fishing activities in Italy, with personal UV dosimeters and a simple formula to calculate the fraction of ambient erythemal UV dose received by the workers. The potential individual UV exposure of the fishermen was between 65 and 542 Joules/m2. The percentages of the ambient exposure were estimated between 2.5% and 65.3%.

A new hybrid nanocomposite material was developed to monitor the effects of UV-C radiation on space-grade structures. Ultraviolet radiation represents one of the most critical limitations for human space exploration and survival. In particular, the UV-C band with shorter wavelengths (100-280 nm) can severely damage materials and life in space. Ultraviolet sensing films were realized using graphene nanoplatelets (GNPs) as signal transducer and DNA as biological sensitive component.
