The menu at the top of the GeigerGraph for Networks includes menus for files, user setup, view, network and help.
GeigerGraph for Networks is a program created by a company called Mineralab. It is distributed through a subsidiary called GeigerCounters.com. GeigerGraph is used to create a network of automatic monitoring stations on a volunteer basis for reading and uploading counts per minutes Geiger counter readings. The main focus is on the continental United States but there are additional monitoring maps for Alaska and Hawaii, Europe, Japan and Australia.
Continuing concern over radiation exposure sparked by the Fukushima disaster has led to a number of programs to monitor radiation across the United States. One of these programs is called the Radiation Network at www.radiationnetwork.com. The home page displays a map of the continental United States.
Let us start from the assumption that you now have a hand-held Geiger counter and you want to make readings. Here are some tips:
Background Level
In order to accurately measure radiation with a Geiger counter, we must start with the normal background radiation. Background radiation comes from both natural and man-made radioactivity. Previous posts have detailed various sources from both of these types. The actual regular background radiation varies from place to place on the surface of the Earth. It also varies with time depending on the weather, the seasons and human activities.
There are many manufacturers who market many different models of Geiger Counters. Websites have been created that bring together selections of different models with comparisons of features.
