Which might mean taking your clothes off, and that might seem an odd thing to do but you can remove 90% of contamination by doing that or having a shower. chemical munitions, those things that deliver it like artillery shells or mortars, they don t explode, they don t do a big bang, they do a pop so that is an indication. we are trying to get some stuff into ukraine where people have simple detectors so they can work out whether it s chlorine or a nerve agent like sarin. i personally think putin will use what we call toxic industrial chemicals, readily available chemicals like chlorine because there is millions. thousands of tonnes of chlorine in ukraine so of course it can be deniable. whatever chemical he uses to attack, no doubt he will of course blame the ukrainians for doing it. but i hope, if they follow some basic rules, then it will be a lot less effective and i hope the russians ....

"Full field X-ray Scatter Tomography" by Gary Ruben, Isaac Pinar et al.

In X-ray imaging, photons are transmitted through and absorbed by the target object, but are also scattered in significant quantities. Previous attempts to use scattered X-ray photons for imaging applications used pencil or fan beam illumination. Here we present 3D X-ray Scatter Tomography using full-field illumination for small-animal imaging. Synchrotron imaging experiments were performed on a phantom and the chest of a juvenile rat. Transmitted and scattered photons were simultaneously imaged with separate cameras; a scientific camera directly downstream of the sample stage, and a pixelated detector with a pinhole imaging system placed at 45° to the beam axis. We obtained scatter tomogram feature fidelity sufficient for segmentation of the lungs and major airways in the rat. The image contrast in the scatter tomogram slices approached that of transmission imaging, indicating robustness to the amount of multiple scattering present in our case. This opens the possibility of augmentin ....
