which, since Oct. 1st has put into operation a national radiation monitoring system by means of which it keeps tab on the varying amounts of radioactive substances floating about in different parts of the country.
The new method is versatile enough to uniformly coat substances of varying shape, size, structure and composition, say the researchers, and can be applied equally to organic and nonorganic compounds — even living ones.

Three test substances of varying sample weight were routinely analyzed within each treatment.
But in the decades since, P&G researchers have found they can produce all sorts of substances by varying the oils used, the amount of pressure applied to them and the chemical conditions in which they are mixed.
The LCF analysis should be taken as semi-quantitative at best, since non-uniform distribution of substances and varying penetration depth of the photon will contribute to the uncertainty.
