AN interactive map shows the hotspots of a radioactive gas in the North-East which is colourless, odourless and tasteless.

Radon is formed by radioactive decay from the small amounts of uranium that can be found naturally in all rocks and soils - it means that it's everywhere.

Public Health England, however, states that 'every building contains radon but the levels are usually low - the chances of a higher level depend on the type of ground.'

The radiation emitted from the elements can increase the risk of cancer and it appears that those living in rural areas are surrounded by more levels of this radioactive gas than more urban areas like London.

Public Health England has released a map showing where high levels are more likely - this can be found through this link. 

The darker the colour, the greater the chance of a higher level. The chance is less than one home in a hundred in the white areas and greater than one in three in the darkest areas.

A broad look at the North-East and North Yorkshire shows fairly low levels of radon across the regions, but there are a number of hotspots.

Stockton

The area of Stillington, near Stockton is one of the region's hotspots - Public Health England say the maximum radon potential here is between 10 and 30 per cent.

Castleside, County Durham

The area around Castleside, near Consett, in County Durham is also highlighted - Public Health England say the maximum radon potential here is between 10 and 30 per cent.

Barnard Castle, County Durham

Parts of Barnard Castle see the maximum radon potential go beyond the 30 per cent, while the slightly lighter area sees radon potential of between 10 and 30 per cent.

Weardale, County Durham

Parts of Weardale, including in Stanhope and Wolsingham, have a maximum radon potential of between 10 and 30 per cent.

Richmond, North Yorkshire

In North Yorkshire, much of Richmondshire has reported a radon potential of between 10 and 30 per cent - Colburn and Richmond are among hotspots in the district. 

Am I at risk from radon?

If you are concerned about the radon risk in your area, you can purchase a Radon Risk Report for £3.90 from the Government website. This will tell you if your home is in a radon affected area.

If it is, the Government will recommend the radon concentration in your home being measured.

You will be posted two detectors to place in your home one in the living area and one in an occupied bedroom.

After three months you post the detectors back to the body in a prepaid envelope provided. The detectors are analysed and the results are posted back to you. The cost is £50.40 and can be ordered through this link.
