As a result, major shielding is suggested around the MI30 slow extraction point. There are number of uncertainties in the the model used in the present analysis. One major uncertainty arises from the radiation source point. We have used point source of iron target of 15 cm radius and 4 m in length. Hence, it may be necessary to take into account these details in the final calculation.
Considerable improvement is anticipated in if such an extended source is used.
Further work is being carried out in this regard.
