All data on RTDN.org comes from other sources and user contributions. Please consider the source and the possibility of significant inaccuracy when using this data.

Readings
We too have been watching events unfold in Japan. We have created this site in an effort to display the reliable data readings as they become available. Although we are careful to evaluate new data sources, we welcome new reliable data from those on the ground in this crisis.
To submit readings
1) Purchase a radiation detection device.
  • INTERNATIONAL MEDCOM
  • AMAZON
  • LAB SAFETY SUPPLY
  • COLE-PARMER
    • 2) Take readings in your area.
    3) Post readings to RDTN.

    About RDTN.org

    This ongoing crisis has highlighted the need for trusted sources. With conflicting reports of radiation levels in affected areas, we wanted to build a way to report and see data in an unbiased format.


    This site is not meant as a replacement for government nor official nuclear agencies. Our hope is that data sets from various sources can provide additional context to the official word in these rapidly changing events. We welcome your thoughts on how to improve the site/functionality and appreciate your work to provide a richer understanding of this crisis. We will continue to implement improvements and functionality as necessary.


    If you are a member of a government agency or a scientist and would like to contribute data or analysis in an official capacity to this site, please contact us here: info@rdtn.org.

    Credits & Thanks
    We have been fortunate to have been introduced to a few really amazing people who have been willing to listen to our idea, put us in contact with others, and help make this project a reality In addition to these new colleagues, we have also been working closely with many old friends on this. Thank you to everyone who has helped out in any and every capacity.

    While we hope to gather data via our own website, we recognize the efforts of others out there who are actively seeking and parsing data and making it available for others to use.


    We are aware that reliable data is critical, and have carefully chosen partners in supplying information. Our map is populated with data from Pachube and Marian Steinbach. . As more reliable data sources become available, we will consider adding further sources to the site. Please note that we are unable to verify our data or sources, and that the data is provided as-is without warranty of any kind.
