Personnel safety is of utmost importance. ¨e team members handling, transporting, and analyzing the CBRNE/TIC evidence must have a thorough understanding of the potential threats posed by the evidence. ¨e same applies to all other CSIU personnel handling the evidence post collection. Finally, CSIs must understand that the receiving laboratory will not accept the evidence until four basic but critical characteristics of each item of CBRNE/TIC evidence have been determined. ¨ink of these characteristics as questions you would want to know for your safety:
• Is this evidence radioactive? • If it is radioactive, what type of radiation is it suspected of being,
α, β, γ, or neutron? • Do we have an idea of the type of isotope? • Finally, what are its energy or activity and dose rate?
