While Tories distract us with Brexit, the NHS has just slipped out its first price list for treatments

Don’t say you weren’t warned.

Pride's Purge

Please don’t say you weren’t warned.

Because you’ve been warned time and time and time again the Tories are stealthily privatising the NHS.

This doesn’t mean just handing over hospitals and NHS services to private firms.

It means stealthily introducing actual charges to NHS patients at point of need.

This is all totally ignored by the mainstream press of course.

NHS trusts are now so confident they’ll get away with it, they are openly publishing the very first price lists since the formation of the NHS – for NHS operations, NHS procedures and NHS consultations (see here):

PLEASE SHARE if you care about the NHS. Thanks.

Atmospheric Muons as an Imaging Tool

Posted in The Universe and Stuff with tags , , on June 19, 2019 by telescoper

The other day I came across an interesting paper with the above title on the arXiv. The abstract reads:

Imaging methods based on the absorption or scattering of atmospheric muons, collectively named under the neologism “muography”, exploit the abundant natural flux of muons produced from cosmic-ray interactions in the atmosphere. Recent years have seen a steep rise in the development of muography methods in a variety of innovative multidisciplinary approaches to study the interior of natural or man-made structures, establishing synergies between usually disconnected academic disciplines such as particle physics, geology, and archaeology. Muography also bears promise of immediate societal impact through geotechnical investigations, nuclear waste surveys, homeland security, and natural hazard monitoring. Our aim is to provide an introduction to this vibrant research area, starting from the physical principles at the basis of the methods and reviewing several recent developments in the application of muography methods to specific use cases, without any pretence of exhaustiveness. We then describe the main detector technologies and imaging methods, including their combination with conventional techniques from other disciplines, where appropriate. Finally, we discuss critically some outstanding issues that affect a broad variety of applications, and the current state of the art in addressing them.

This isn’t a new field, but it’s new to me and this paper provides a very nice introduction to it. I’ve taken the liberty of reproducing Figure 3 here to show one application of `muography’..
