After the Election, Congress Must Help Victims of Radiation Exposure by Passing RECA

Union of Concerned Scientists

Next week, October 15 is the anniversary of the enactment of the Radiation Exposure Compensation Act (RECA). They brought a summary of medical costs with them, showing what they’ve spent on health care and associated costs for their radiation-linked illnesses.

Why the World Needs a New UN Study on the Effects of Nuclear War

Union of Concerned Scientists

New scientific information has yielded insights, including updates to our understanding of, and ability to model, the atmosphere, and the studies of the long-term effects of radiation on affected populations have yielded new information.

Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

Albedo is the total reflection of incoming solar radiation by Earth. As industrial aerosols decreased due to this new regulation, particularly over the North Atlantic Ocean, the planetary albedo slightly decreased, which means that more incoming solar radiation was absorbed by the planet rather than reflected. What is albedo?

Introducing the non-radiating antenna

Physics World

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.

How Do ‘Future Climate Scenarios’ Shape Climate Science and Inform Policy? 

Union of Concerned Scientists

Initially it used four different emission storylines from the Special Report on Emissions Scenarios (SRES) as a scientific basis, however, recognizing the need for a more flexible and policy-relevant framework, scientists developed the Representative Concentration Pathways (RCPs) for the IPCC reports.

Terahertz radiation drives compact ultrafast electron diffractometer

Physics World

The team, led by Dongfang Zhang and Franz Kärtner at the Center for Free-Electron Laser Science in Hamburg, created their instrument by compressing bunches of electrons to ultra-short durations, using millimetre-wavelength terahertz radiation. Terahertz manipulation. Highly synchronized. The instrument is described in Ultrafast Science.

Novel brachytherapy device treats eye cancer with intensity-modulated radiation

Physics World

Plaque brachytherapy treatments deliver radiation to eye tumours via radioactive sources called pellets or seeds, which are placed in a device called a plaque that is sewn onto the surface of the eye. The post Novel brachytherapy device treats eye cancer with intensity-modulated radiation appeared first on Physics World.
