Quick research for data collection and processing it

Scenario for Design Challenge
The United Nations has brokered a treaty with many nations that reinforces and strengthens controls on production of material that may be associated with the development of nuclear weapons. Part of this treaty stipulates the enforcement of these controls in signatory countries through the use of technical means. This has been interpreted by the enforcement agency as allowing the use of covert data collection in suspect areas for confirmation of treaty compliance.
Your company has been selected by the United Nations enforcement agency to design a system to do a very specific element of this covert data collection: collection of sensed data resulting from the specific radioactive signature of treaty covered material.
The customer supplied requirements are that your system will be required to do the following actions:
1) while in place, detect radioactive particles of a specific nature (collect target specific data)
2) perform preprocessing on the collected data in order to contextualize meaning
( IN OTHER WORDS, YOU MUST DO RESEARCH ON HOW WE GONNA COLLECT THE DATA PROCESS IT (IN DETAILS)
