OneRADON is an application designed for use with Sun Nuclear's suite of Professional Continuous Radon Monitors – Models 1027, 1028, 1030, and the latest Model 1028-XP.

The fully-featured app allows retrieval of test data and enables users to generate custom PDF test reports and invoices with ease.

Further streamlining workflows, OneRADON allows import of data into pre-configured report templates, review and editing of archived reports, and enables users to send test data and reports to the OneRADON desktop client software.

Report setup function includes: start and stop time selection for any individual test; inclusion of data tables and charts in reports; custom report checklist generation; and inclusion of detailed property information with pictures and test conditions. To minimize repeated user clicks, the application offers a one-time preference setup, which manages Radon unit levels of choice, action levels, detailed company information with header and signature pictures, and more.

1027 users have now the option to manual enter the device serial number and calibration factor to be used in all reports as well as optional adjustment of test start time during data retrieval. If you use a 1030 or 1028-XP the application allows to clear data from monitor memory, and start a new test directly from the application including setup of all test parameters.

The report itself

The app works good. However, the final report given to the clients could be a much better layout. The writing is a very small font. Hard to read. The test results should have a large result that’s very easy to read and understand for the clients on the first page. I’m a local Realtor and inspector and think I could help make this look much more appealing. Jason Barnett KCMO

App is great! Brandon took a few mins to walk me through the applicable set up steps and the rest was very intuitive. This should save time and flows well with the iPad functionality. Thank you!

Unisable insulting half effort to the radon community

The tiny six point font reports are illegible and are not accepted in a house closing as a valid document.
No clear setup instructions. Unusable with the 1027. Clunky and unpresentable with the 1028. Sorry sun nuclear.

Thank you for your feedback and sorry to hear you are having difficulties. Please, instructions are available at We do our best to adapt previous generation technology (RS232 and USB 1.0) to be compatible with today's generation of wireless mobile phone technology and in particular with Apple. We designed the mobile software in such a way that it can connect to all older generation monitors and can use the same user workflow to generate reports independent of what monitor you connect with. Please, let us know what differences you experience in user workflow between 1028 and other monitors and we will do our best to incorporate your suggestions. Also, please, can you point us to the guidance documents you mentioned what font sizes you feel are acceptable. Our font sizes are similar to font sizes you can find on HUD statements or similar.
