Revision as of 14:26, 14 January 2011

Scope

Mortality due to indoor radon concentrations.

• Spatial: Europe
• Temporal: years 2010-2050

Definition

• Lung cancer cases calculated from radon concentration using <math>cases = impact function * concentration * population</math>. IF taken from HEIMTSA and INTARESE (Darby 2004; Darby 2005).
• The referenced impact function is scaled down in assuming only 4.6% of population is exposed, but we assume all are exposed.

Data

Dependencies

• Radon concentrations in European residences
• Population of Europe
• Lung cancer mortality in Europe (from WHO mortality data)
• ERF of radon exposure on lung cancer mortality (heande:ERFs of several pollutants), impact function on the same page used for code below.

Unit

cases per year

Formula

R code

• This code features R functions described on pages Opasnet Base Connection for R and Operating intelligently with multidimensional arrays in R.
• Possible extensions, to accomodate more complex models, are left commented out with # for now.
