Some of you have already monitored one or more cities and you have submitted your data as well. Below are two ways that the data can be shared. One is in a table and the other as a map. There are many more ways to show data and we will explore them once all the data for April have been submitted.
The color coding used in the BRAG scale is as follows:
Green for values below 1,000 microW/m2;
Amber for values between 1,000 and 10,000;
Red for values between 10,000 and 100,000; and
Black for values above 100,000 microW/m2
Green (1000 microW/m2) is the guideline recommended in the Salzburg Resolution (2000) and by the BioInitiative Report (2007) for long-term exposure and is based on the precautionary approach.
Black (100,000 microW/m2) is the guideline recommended by Russia, China, Italy, Switzerland, most of Eastern Europe, as well as the city of Toronto and is based on biological effects.
Values that exceed 10,000,000 microW/m2 are in violation of the guidelines in most of Western Europe and in the U.S. and this guideline is based on a thermal or heating effect.
For maps, we are going to convert the data for each main street into three values and these three values will be color coded and represented by 3 concentric circles. Those three values include the highest average reading at a corner (center circle); the median of the maximum readings (which means that half of the maximum readings are below and half above this value); and the highest maximum value recorded (outer circle). This may sound complex or confusing but there is reason for this madness and we can discuss this at the next ZOOM meeting in early May (date yet to be set).
Please be careful submitting your data. Should you make a mistake but not notice it before you hit the submit button let us know and we can correct the error.
Below is a Table and a Map of the World showing some preliminary data. We are going to use maps with much finer detail with each country and each state represented individually but for now we are using the world map.
Note that the Table has an error in it (shown in red). We will be able to pick up some of these errors but please double check you values before you submit the data.
For those of you monitoring one or more cities over time, we will provide individual tables and graphs for you and we will post them on this website.
Keep the data rolling in …
