An international team of physicists has created what might seem like a contradiction in terms: a non-radiating source of electromagnetism. Maxwell’s equations tell us that accelerating charges radiate energy in the form of electromagnetic waves. cm above the non-radiating source prototype.

A technology called monochromatic X-ray imaging could reduce radiation dose per mammogram by a factor of five to 10 times, according to a research review published in the European Journal of Radiology. However, the radiation delivered by the technique has been a focus of debates regarding possible cancer risk associated with breast screening.

Monitoring Radiation Risk Modeling and calculations using accepted scientific methods show any radionuclides emitted into the air will not pose a health risk. Radiation monitors will be placed in six onsite locations and will measure 24 hours a day, seven days a week, and be analyzed regularly, DEP explained.

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium.
