• 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….

67. – 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.”
