That is long enough to see that there has been a noticeable trend in the Earth’s Energy Imbalance (EEI), mostly driven by a reduction in the solar radiation reflected by the planet, while the outgoing long wave radiation does not appear to contribute much. But what can be causing this? A paper last year (Goode et al.,

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.

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.

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.

Tsang noted that automation in radiotherapy is a popular topic, with the number of published studies on this theme increasing from 30 in 2011 to 381 in 2021, and many talks in this area at the ESTRO congress. Fewer, higher radiation doses safe for early breast cancer. Machine learning makes its mark on medical imaging and therapy.
