Mather type plasma focus with the bank energy, 150 kJ (30 kV, 333 μF), was studied for the induced activity of 18 F, a short-lived radioisotopes which is a β + emitter with 511 keV of gamma rays and has a half-life t 1/2  = 110 min, through 16 O( 3 He,p) 18 F and 20 Ne(d,α) 18 F nuclear reactions. The results of simulated numerical computations show that activities of 3.786 × 10 10 Bq and 6.632 × 10 10 Bq were found for 16 O( 3 He,p) 18 F and 20 Ne(d,α) 18 F reactions, respectively. The calculations were carried out for the same initial and final energies conditions, when Plasma focus works with 150 kJ at the repetition rate of 1 Hz and for 120 min of running time. According to the simulated results, the activity of 20 Ne(d,α) 18 F had an increase because the projectile ion mass “deuteron” was lighter than the 3 He which resulted in the higher induced voltage and the number of projectile ions.
