Workers operations and corresponding duration for dose calculation.
| Number | Activity | Duration of activity if the automatic cutting equipment is used, min | Duration of activity if the manual cutting equipment is used, min |
| (1) | Preparation for cutting upper or lower ellipsoid | — | 2 ± 0.5 | (2) | Cutting upper or lower ellipsoid into two pieces* | — | 18.6 ± 2.0 | (3) | Preparation for radial cutting | 5 ± 0.5 | 3 ± 0.5 | (4) | Radial cutting* | 27.8 ± 2.3 | 37.3 ± 4.1 | (5) | Preparation for vertical cutting (four times) | 6 ± 1 | 2 ± 0.5 | (6) | Vertical cutting (four times)* | 13.1 ± 1.1 | 17.5 ± 1.9 |
