Woman scientist with break-in career finds solution for nuclear weapons in dust particles

 Dust can reduce the effect of nuclear weapons. This has been proved by a woman scientist who came back to science after a hiatus of one year.

Such a break is common among Indian women who prioritise family over their career due to various circumstances, which are usually typical to the gender. The Women Scientist Scheme (WOS A) fellowship of the Department of Science & Technology (DST) provides opportunities to women scientists and technologists who had a break in their career but desired to return to the mainstream.
Dr Meera Chadha from Netaji Subhas Institute of Technology, New Delhi, availed this opportunity not only to return back to mainstream science after a career gap but also to show for the first time, through mathematical modelling, that the deadly effects of nuclear weapons can be partially mitigated or reduced with the help of dust particles.
Her recent study published in the ‘Proceedings of Royal Society A, London’ illustrates the reduction in energy released and damage radius from an intense explosion (nuclear explosion in particular) by introduction of dust particles. She has shown how the blast waves from the explosion decayed in the process.
