TABLE 1.
Differentiation of gamma radiations and electron beam radiations (Dahlan, 1994).
| Sr. No | Characteristics | Electron beam | Gamma radiation |
|---|---|---|---|
| 1 | Energy | 1.17 + 1.33 MeV | Variable 0.2–10 MeV |
| 2 | Power | 1.48 kW/100 kCi | Variable 4–400 kW/unit |
| 3 | Dose rate | Low (Mrad/hr) | High (Mrad/sec) |
| 4 | Penetration | High (43 cm in water) | Low (−0.35 cm/MeV) |
| 5 | Energy utilization efficiency | Low (−40%) | High (−90%) |
| 6 | Production rate | Low | High |
| 7 | Maintenance | Replenishment of Co-60 source | Replacement of electronic parts |
| 8 | Others | Source decay 1%/month | Shut-off power source |
