Radon Gas Infiltration

Radon is an odorless radioactive gas that results from the natural breakdown of uranium in the soil. Uranium is present in most of the soil and rock around the world. It is typically concentrated in areas with lots of granite, shale, phosphate and pitchblende.

The gas is a deadly carcinogen, estimated to cause up to 14% of all lung cancers in the world, making it the second leading cause of lung cancer after smoking. Studies show that sealing the sump and the floor drain eliminates the major source of radon infiltration to the new buildings and reduces radon in existing buildings.

• Radon is invisible, odorless, and tasteless.

• Radon gas comes from the decay products of uranium in the ground beneath buildings. It can seep in through cracks, sumps, joints, floor drains, or other tiny openings in foundations.

• Radon gas emits radioactive particles that can be inhaled into the lungs. The adverse health effect—lung cancer—may not be produced immediately. An estimated 250 deaths from lung cancers each year in Ireland are linked to exposure to radon - a higher number of fatalities than is caused by road traffic accidents.

• One in 15 houses have elevated radon levels; however, in some counties, it is over 50% of homes. Elevated radon levels have been discovered in every county in Ireland.

According to Trinity College scientists, Ireland has some of the highest recorded indoor levels of Radon in Europe and probably the eight highest globally leading to 1 in 10 of the population being at risk from unsafe exposure to indoor radon gas.


The Green Drain™ can help to prevent harmful radon gas infiltration through unprotected drains. The Green Drain™ is an economical Drain Trap Seal Device that allows water to flow down the drain while preventing Pests, Odors, and Harmful Gases/Pathogens from infiltrating the living or work space.
