Background: Evidence suggests that children are more susceptible to radiation risks or hazards. In particular, their gonads are more sensitive to the effects of radiation, especially at or below reproductive age. Protecting the gonads of children and adults is of particular importance to the imaging. Aim: To investigate level of the use of gonad protection during paediatric abdomen and pelvic X...

In light of global climate change, ecological studies increasingly address effects of temperature on organisms and ecosystems. To measure air temperature at biologically relevant scales in the field, ecologists often use small, portable temperature sensors. Sensors must be shielded from solar radiation to provide accurate temperature measurements, but our review of 18 years of ecological litera...

The article aims at constructing protective composite shields for breasts in chest computed tomography and investigating the effects of applying these new bismuth composites on dose and image quality. Polyurethane and silicon with 5% of bismuth were fabricated as a protective shield. At first, their efficiency in attenuating the X-ray beam was investigated by calculating the total attenuation c...

Abstract Background Lead particles from hunting rifle ammunition become embedded in the tissue of shot animals and pose a health risk to predators scavengers that eat discarded offal or parts non-retrieved carcasses game animals, as well humans who consume game. Copper copper–zinc alloys are most widely used alternatives leaded ammunition. In Denmark, there has been growing awareness toxic envi...
