What is Radon Gas?

• Chemical element radiaoctive and gaseous

• Granite origin, granite areas, mining.

• From U238 and Ra226 (solids) Rd222 (Gas)

Poliuretan S Spray S-35RGB/ECO Barrier Against Radon Gas

Poliuretan S Spray


What is the main problem?

• In the atmosphere the low concentration of Rd is not a problem

• Confined spaces HOUSES, concentration could be HIGHER

Why?

Inhalation of Radon (Po218 and Po214) Alpha Particles

• Provokes LUNG CANCER

• USA consideres 2nd cause of Lung Cancer after smoking

• In Europe: Germany, France, Sweden, Holland, Spain, ….

» In 1987 (EPA) and 1988 (IARC):

Radon Gas was declared a Human Carcinogen 7


Poliuretan S Spray


How to solve it?

• Waterproof membrane or barrier against Rd gas.

• Penetration Control. How much? Diffusion Coefficient of Gas Rd.

D= 10-15 - 10-8 m2/s.

• Diffusion Length (mm) L. German Standard states:

The thickness of barrier must be 3 x L in order to guarantee < 1-2 % atoms.

Requirements from Europe:

Recommendation is 400 Bq/m3

New houses built are 200 Bq/m3 (EPA in USA says 148 Bq/m3)

WHO: Goal is 100 Bq/m3
