• Every data point must have a time stamp and GPS coordinates.
• Device and user must have unique IDs to provide ability to identify and track errors (user can remain anonymous but still needs ID)
• The device used must have publicly available specs, including sensor type, size, and manufacturer.
• Data submitted to Safecast must be formatted correctly with all applicable metadata.
• Measurements should be taken at approx 1m height, with safeguards against interference, etc.
• Measurements should be given in CPM, and note what kind of shielding (if any) was used.
• A single measurement cannot represent the levels of an entire city

“…crowdsourcing, for example in the collection and dissemination of radiation data, can also help to instill confidence
in information from official sources. But to continue to be effective, these public
groups need to maintain their independence; to be seen to work too closely with the authorities will diminish
their effectiveness, and consequently also their credibility, making them redundant….
– I E M 6 R E P O R T ( C O N T )
“…For government authorities and agencies, crowdsourcing certainly is the
‘genie that will not go back in the bottle’. It is necessary to accept that this technology is here to stay and that empowerment of
the public is not necessarily a negative development.”
