The appendix provides information on the various technologies that can detect radiation and confirm the presence of contamination on personnel or in the environment. More information can be found at https://jacks.jpeocbd.army.mil/ No single device can detect all forms of radiation and no one device is useful in all situations. Radiation detection devices detect and measure the following: 1) specific types of radiation, (e.g., alpha, beta, gamma, neutron), 2) specific levels (or ranges) of radiation energy (in keV, MeV) 3) "Counts" per unit time (minute or second) 4) Roentgens (R) per unit time (e.g., milliroentgen per hour [mR/hr]) 5) cumulative dose (in units of gray or rad) 6) dose rate (in units of gray or rad per unit time).
