Investigation of 18F and 13N Radioisotopes Production Using Cyclotron Recirculating Liquid Target [PDF]

مجله علوم و فنون هسته‌ای, 2017
Two radioisotopes of 18F (T1/2=109.7 min, Iβ+= 97%, Eβ+= 0.63 MeV), and 13N (T1/2=10min, Iβ+=100%, Eβ+=0.96 MeV) decay almost completely via positron emission. Due to this characteristic, these radioisotopes are used in PET (positron emission tomography)
