(3) tight or Radon measure if [mu](B) = sup{[mu](F): F [subset] B, F [member of] [exp.sub.c](X)} for every B [member of] Bo(X). For every Radon measure [mu] on X there exists a unique Radon measure [beta][mu] on [beta]X such that [beta][mu](H) = [mu](H...

A linear form μ on the space of complex-valued continuous functions with compact support H is a Radon measure if, for every compact K X , the restriction of μ to the space of continuous functions with support in K is continuous. Every positive linear form on H is a Radon measure (...
How do you measure atmospheric radon? Before we get into specific techniques, let’s first talk about some measurement units. One that is commonly used is the Working Level, or “WL”. What is a WL? It is the energy associated with the decay of radon daughters (progeny) in air. ...
Follow the two steps in our mission for piece of mind: measure and mitigate. There are several test methods available for radon testing, ranging from 2 days to 90 days in length. Watch this brief video from Dr. Roberta Bondar for more information about Radon and the importance of testing....
5,8* E-mail: wiki@natur.cuni.czThe electrostatic collection is based on the principle of collection of 218 Po using an electric field on a semi-conductor detector and measure on-line the the radon activity in the air. Polonium is collected from a positively charged sphere or hemisphere, ...
An attractive alternative to the gamma spectrometry method of detection has been to use liquid scintillation counting to measure the radon and daughters trapped by activated charcoal (Prichard et al., 1980; Prichard and Marien, 1985). The liquid scintillation charcoal technique offers greater ...
Radon Systems Of Connecticut Puts Your Safety First! Although radon is not visible and you cannot smell it - it is not too hard to find out if you have a radon problem. We use state of the art testing that is approved to measure the amount of radon in the air. The EPA suggests mea...
In Part I we consider a class of subsets of a topological space X and a Radon measure on X; if it is known that, for sufficiently many \\(T \\subseteqq X\\) , the restrictions of the sets in constitutes a uniformity class in T w.r.t. the restriction of the given measure, ...
