Sentence examples for working level month from inspiring English sources

In the mining industry, the exposition is traditionally measured in working level (WL), and the cumulative exposition in working level month (WLM); 1 WL equals any combination of short-lived 222Rn progeny (218Po, 214Pb, 214Bi, and 214Po) in 1 liter of air that releases 1.3 × 105 MeV of potential alpha energy; one WL is equivalent to 2.08 × 10−5 joules per cubic meter of air (J/m3).

The unit for cumulative exposure is the working level month (WLM).

The excess relative risk (ERR) per working level month (WLM) was estimated as 0.21%9595% CI: 0.18 0.24).

This JEM includes information on exposure to radon and its progeny in working level month (WLM), external gamma radiation in mSv and long-lived radionuclides in kBq h m−3 (HVBG and BBG, 2005; Lehmann et al, 1998).

Poisson regression modelling has been applied to the following exposure groups: < 10 WLM (Working Level Month); 10-49 WLM; 50-149 WLM; 150-299 WLM; > or = 300 WLM; it indicates an increase in the SMR for lung cancer of 0.6% per WLM (standard error: 0.4%) with an estimated intercept at 0 WLM of 1.68 (standard error: 0.4).

The most recent analysis has shown that, in common with other cohorts of radon-exposed miners, the excess relative risk of lung cancer per working-level month is modified by age and time since exposure.

Three recent analyses of the data from the cohort have led to rather different estimates of the excess relative risk of mortality from lung cancer per working-level month.

A pooled analysis of 11 miners' cohorts revealed a linear increase of risk with increasing cumulative exposure, while the excess relative risk (ERR)/working level month (WLM) decreased constantly with increasing time since exposure and increasing attained age.

"We have improved the results but we kept working hard through October and November trying to get the fitness levels higher," Ardley added.
