Measure

​

A radon measurement is easy to complete, make sure you use a validated laboratory . Public Health England runs a validation scheme for laboratories and is a validated laboratory too

 

 if you choose to test with TJR Ventilation Solutions we will post you 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 us in the pre-paid envelope provided. We organise that the pods are analysed the detectors and post the results to you: the cost is £50.00 inc. VAT (£41.67 plus VAT).

​

Radon detectors are safe and simple to use: e.g., they can sit on a shelf. The hollow plastic shell contains a piece of clear plastic that records the damage caused by radon. The detectors do not emit anything and do not collect anything dangerous. However, they can be damaged by heat or submersion in water and should not be opened.

​

The test

​

The amount of radon varies over time and from room to room in a home. The test is carried out over three months to allow for variations in levels. The test is to determine your exposure, this is why we recommend testing the living area and bedroom as these are the rooms you and your family use the most. Order a domestic measurement pack or workplace measurement pack.

 

Short-term testing

​

Radon levels in houses vary substantially from day to day as they are influenced by weather conditions. The Action Level refers to the annual average concentration in a home. For this reason, it is preferred that radon measurements are carried out with two detectors (in a living area and bedroom) and are conducted over a reasonable period of time, typically three months. This averages out short-term fluctuations. Tests that are carried out over shorter periods will have greater uncertainty and are more likely to lead to ambiguous and inconclusive results.

​

The result

​

We aim to post the result and an explanation to you within four weeks of you returning the detectors to us. The result will give the yearly average radon level in your home and will tell you whether it is above or below the Action Level. The results will be less reliable:

• If there is a change of occupier during the test period

• If the home is unoccupied for more than a few weeks in the three months

• If there are on-going building works

• If the detectors are not put in place within a week of arriving

• If the test period is shorter than 3 months

If the result is near to or above the radon Action Level, we will provide information on radon remedies.
