Over 400 scientists from across the country sought a clarification from the Rashtriya Kamdhenu Aayog’s chairman Vallabhbhai Kathiria to explain how radiation will be reduced by keeping cow dung chips on cellphone. In an open letter, scientists from many renowned institutions across the country including IIT-Bombay, Tata Institute of Fundamental Research and Indian Institute of Science Education and Research, asked: “Where and when were the said scientific experiments done? Who were the principal investigators? Where were the findings published? If it was in a research journal, was it peer-reviewed? Can the data and experimental details be provided?”
