More from this interview:

In the case of Pokhran-II, we tested our thermonuclear device at a controlled yield of 45 kt, as the Khetolai village was just about five kilometres away and we had to ensure that the houses in the village, which had a population of about 5000 people would suffer negligible damages. The army was informed that the villagers need to be told to step out of their houses during the tests. This was a difficult task as we had to maintain secrecy. But none of the villagers questioned or complained.
