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

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 south London shows low levels of radon, with hotspots in some areas.

Here are how some locations in North Hampshire fare according to the map:

Chineham

Basingstoke Gazette:

Some parts of this 1km grid square are in bands of elevated radon potential. Maximum radon potential is 1-3%. 

Basingstoke Central, Black Dam, Eastrop and Kings Furlong

Basingstoke Gazette:

There is a predominately low risk of radon around the area.
All parts of this 1km grid square are in the lowest band of radon potential. Less than 1 % of homes above the Action Level.
