Related to spallation: Spallation reaction

spallation

(spă-lay -shŏn) A particularly vigorous type of nuclear reaction in which several particles or nuclei result from a high-speed collision. Spallation occurs when cosmic rays collide at high speed with atomic nuclei, the heavier nuclei breaking up to produce lighter nuclei.

spallation

[spȯ′lā·shən]
(nuclear physics)
A nuclear reaction in which the energy of the incident particle is so high that more than two or three particles are ejected from the target nucleus and both its mass number and atomic number are changed. Also known as nuclear spallation; spallation reaction.

The book looks at what would be the political, social, economic and scientific effects on the Oresund Region (which consists of Copenhagen in Denmark, Malmo in Sweden and the stretch of water in between) of a large scientific research centre looking at spallation, a technique that creates neutrons with the minimum of radioactive danger.
