Irradiation time = 1 h

Beam current = 1 mA
Eg = 162.32 keV T1/2 = 71 d
Ig = 23.3 % Tolerance = 1%

Geometry factor = 1

Irradiation angle = 90 degree

Bombarding Energy of  27.6 MeV

Cooling time = 7 days

Total activity after cooling = 164.8 kBq

Activity of the constant layer after cooling = 38.8 kBq

Specific activity at EOB = 5.704 kBq/mm

Thickness of the layer with constant activity = 6.8 mm
