University of Cambridge, said: "Ionising radiation probably causes all types of mutational damage, but here we can see two specific types of damage and get a sense of what is happening to the DNA. Showers of radiation chop up the genome causing lots of damage simultaneously. This seems...
And they didn't come with a "stereoscope"; you can't view ionising radiation with a View-Master. They came with a spinthariscope. (Perhaps the original piece as written had this right, but a sub-editor helpfully "corrected" it.) That's a simulation, via Theo Gray, of what a spinth...
Acute radiation sickness occurs when your body has absorbed a large amount of ionizing radiation, usually on the order of several sieverts. What makes radiation lethal is the effect it has on DNA. When a high energy particle, be it a photon or some other particle collides with DNA it break...
For high-LET radiation, such as alpha particles from radon decay products, there’s more a priori reason to believe LNT would be a good model, and less empirical evidence suggesting that it is a bad model. It might be hard for the agencies to explicitly disavow LNT in these circumstances....

it is non-toxic and does not require long aeration times. However, gamma radiation can cause degradation of polymers by cross-linking, chain scission or a combination of both. Chain scission occurs in weak polymer bonds as a random rupturing, resulting in the reduction of the molecular weight ...
