New measurement capabilities to protect the marine environment

The EU Marine Strategy Framework Directive (MSFD) aims to protect vulnerable marine ecosystems by limiting underwater noise from man-made activity, such as shipping or construction work, which can adversely affect marine wildlife. The sources of greatest environmental concern radiate most of their sound energy in the low freque...

Detecting contaminants in soil

Land reclaimation and redevelpment is converting old industrial sites for new uses such as housing. Ensuring that no lingering contamination remains and that any found is not redistributed to other locations is becoming increasingly important. Construction companies are required to conduct detailed soil analyses to identify pol...

Fibre-optics for structural integrity

Monitoring the long-term strength of large structures used in the nuclear power industry is essential to safeguard the environment from radioactive contamination. Dykes formed of natural materials such as gravel, clay, or sandy soil provide the constraining banks of major rivers supplying water cooling to nuclear power plant. T...

Nuclear incident alerts

Following a major nuclear incident, fast decisions are needed on issues from protecting the public to prevention of contaminated food entering the supply chain. Different radioactive isotopes, or radionuclides, present different risks. For example, radioactive iodine can accumulate in the thyroid gland, whilst caesium on grass ...

Better optics for UV monitoring

Brewer spectrophotometers are among the most sophisticated instruments currently used to measure stratospheric ozone and solar UV radiation. Global solar UV radiation entering the spectrophotometer is sampled by a diffusion plate to measure its intensity. The diffusion characteristics of this entrance optic is one of the most i...
