This passive cooling effect works under the full sun whenever the insects are exposed to the clear sky. o appreciate the effect of thermal radiation,
says Yu. alf of the energy loss at that moment is due to thermal radiation since your skin temperature is temporarily much higher than that of the surrounding environment.
For instance, the X-ray radiation method cannot detect contaminants with sizes smaller than 1 mm with current practical X-ray levels,
and it cannot be applied for the inspection of foods that have lactic acid bacteria because X-ray radiation causes ionization of such foods.

In the beginning, the idea was to develop a radioactivity sensor for inside a nuclear power station says Tijmen Euser from the Max Planck Institute in Erlangen.
however, that radioactive radiation darkens the interior of conventional glass fibres so that light can no longer propagate therein,
making them unsuitable to measure radioactivity. The glass fibres which we owe particular thanks to for high rates of data transmission
As the air-filled cavity cannot be darkened by radioactive radiation the researchers see PCFS as an interesting alternative to conventional fibre-optic sensors in order to ultimately measure radioactivity as well.
The Erlangen-based physicists examined whether hollow-core photonic crystal fibres are suitable as sensors by initially using the fibres to measure electric fields, vibrations and temperatures.
Fluorescent beads as a sensor for radioactivity In their experiment the researchers used an oven to heat part of the fibre to temperatures of several hundred degrees Celsius.
Next, we want to realize the radioactivity sensor, says Bykov. To do this, the researchers want to use fluorescent beads
which re-emit the radioactive radiation absorbed in the form of visible light. Information on the strength of the radioactivity at the location of the bead would then be provided by the changes in the intensity of the fluorescence.
Bykov sees great potential in the new technology. The spatial resolution would theoretically be limited only by the size of the particle.
