How do you measure radon?

By February 8, 2019 June 4th, 2019 Measurement

Radon is a so-called “inert” gas that is also radioactive. In other words it emits ionising radiation. If people suffer excessive exposure to this radiation in their workplace or at home, it can lead to cell damage and therefore to cancer. It is estimated that up to 14% of all cases of lung cancer in the world are caused by radon. measurements are crucial.

Radon comes from the ground

Radon occurs naturally in the ground since it comes from uranium that decays. Buildings that have basements and that are otherwise in direct contact with the ground are most affected by radon.

Radon is measured using boxes

Radon is normally measured using what are referred to as “radon boxes”. These are small boxes that you place around the home or in the workplace for a certain period of time. This is to see the specific radon value in the specific rooms where the measurement is being carried out.

This means that it is best to place radon boxes in rooms where you spend a lot of time such as bedrooms and living rooms. In rooms in which you or people around you spend the most time, it may be worth placing two boxes in different parts of the room to obtain the most accurate measurement possible.

Quick measurement or long-term measurements

There are two different types of boxes that you can use for radon measurement. The first of these is the box that carries out long-term measurement that most people are familiar with. A so-called “long-term measurement” enables you to obtain an average annual value for radon levels in indoor air. It is only possible to carry out long-term measurements of radon during the winter months. This is because people do not ventilate as frequently as in summer, which concentrates the radon and, in turn, provides an optimum measurement. Long-term measurements take approximately two to three months and all you need to do is position the boxes. Then leave them there for the full period before sending them back.

For people who do not have the time required to carry out long-term measurements, there are also boxes that provide a quick measurement. These do not show the average amount of radon in a year, but can provide a quick indication of the property’s approximate exposure to radon. They are suitable for people who want to buy a house or another property. Quick measurements take up to 10 twenty-four hour periods and can be carried out at any time of year.

After the measurement

When the period of time for the selected boxes has ended, you simply send in the boxes. You then receive a full report on the results. This usually takes only one week to send out.
