An interactive map shows the hotspots of a radioactive gas in Sussex.

Radon - which is colourless, odourless and tasteless - is formed by radioactive decay from the small amounts of uranium that can be found naturally in all rocks and soils.

This means that it is 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.

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 Sussex shows low levels of radon, with hotspots in some particular areas.

This is how our county looks according to the map:

Central Brighton

The Argus:

Some parts of this 1km grid square are in bands of elevated radon potential.

The area currently has one to three per cent risk of homes being at or above the Action Level.

The maximum radon potential is one to three per cent here.

Roedean

The Argus:

Some parts of this 1km grid square are in bands of elevated radon potential.

Maximum radon potential is between three and five per cent.

Hove

The Argus:

Some parts of this 1km grid square are in bands of elevated radon potential.

The maximum radon potential is one to three per cent here.

Shoreham

The Argus:

Some parts of this 1km grid square are in bands of elevated radon potential.

The maximum radon potential is one to three per cent here.

Saltdean

The Argus:

Some parts of this 1km grid square are in bands of elevated radon potential.

The maximum radon potential is one to three per cent here.

Hollingbury

The Argus:

Some parts of this 1km grid square are in bands of elevated radon potential.

Maximum radon potential is between three and five per cent.

Withdean

The Argus:

Some parts of this 1km grid square are in bands of elevated radon potential.
