Radon measurement

Time for us to collect the radon detectors.

Now is the time to collect the radon detectors.

We have placed measuring boxes in over 1,500 apartments and premises. If you have received information about obtaining them, you can get more information here.

Due to the situation with Covid-19, we will not enter the apartments. Therefore, all those who have received radon detectors placed are asked to take the detectors down themselves (2 per apartment) and hang them on the door handle in the stairwell for us the announced pick-up day.

If you do not have the opportunity to collect the detectors yourself, we ask you first and foremost to take help from a related person. In this case, this may be done a few days before collection if necessary.

If you need to contact us, you can easily use the form below, otherwise you can call 08 – 574 300 00.

Use this contact form when contacting us. Useful information could be about pets in the apartment, or other things we need to know when entering your apartment. A

    What is radon and radon measurement?

    Rikshem are obliged to measure radon in their apartments.

    Radon is a radioactive gas that can eventually cause lung cancer. The gas can come from the ground under the house or from the building material and is found all over Sweden. To measure the concentrations of radon gas we place film trays (plastic boxes with a trace film in). In the measuring boxes there is a trace film that records the number of disintegrations in the air, which are then analyzed at a laboratory.

    Does my apartment need to be measured?

    Yes – the selection of the apartment is made to meet the requirements set by the authorities. It is therefore very important that we get access to all apartments.

    How is the measurement carried out?

    We will notify all apartments to be measured. On the day of deployment, we need access. If you won’t be at home we need you to place a key that in the locker on the door or via a service key. We always call / knock on the door before entering the apartment.

    Two measuring boxes are placed out. One is put in the bedroom and one in the living room. Is it a one room apartment we place the measuring boxes in the bedroom / living room and kitchen.

    The measuring boxes should then be in place for about two to three months before we announce the date we pick them up. When collecting, it is usually possible to hang the measuring boxes on the door if you can’t be home, then we do not have to go into the apartment again.

    Need to sleep in?

    We can’t make arrangements about visiting your apartment at a specific time. If you’ve worked late and need to sleep in we ask you to place a note on the door so that we can leave the film trays for you. If so, we need a confirmation from you that the film trays are placed in the apartment which you can use the contact form above for.


    Do you have pets that are home alone, we want to know about it. If it is not appropriate for us to enter the apartment, we want you to contact us to determine how the placement can go – we can in some cases leave the measuring boxes on the door handle so that you place them on your own.

    Home alarm

    Do not forget to turn off any alarms if you are not at home, if the door has multiple locks make sure you only lock the one we can unlock.
