skos:definition "The 'activity concentration' of 'radon' or 'thoron' in 'radioactive equilibrium'<br/>
with its short lived progeny that would have the same <i>potential alpha energy<br/></i>concentration as the actual (non-equilibrium) mixture.<br/>
The 'equilibrium equivalent concentration' of 'radon' is given by<br/>
'EEC radon' = 0.104 × 'C'(218Po) + 0.514 × 'C'(214Pb) + 0.382 × 'C'(214Bi)<br/>
where 'C'('x') is the concentration of nuclide 'x' in air. 1 Bq/m3 <i>EEC radon<br/></i>corresponds to 5.56 × 10–6 mJ/m3.<br/>The 'equilibrium equivalent concentration' of 'thoron' is given by<br/>
'EEC thoron' = 0.913 × 'C'(212Pb) + 0.087 × 'C'(212Bi)<br/>
where 'C'('x') is the concentration of nuclide 'x' in air. 1 Bq/m3 <i>EEC thoron<br/></i>corresponds to 7.57 × 10–5 mJ/m3. <br/>" (en)
