In 1980 she moved to McGraw-Hill in New York as an associate editor for the industry newsletters Nucleonics Week, NuclearFuel and Inside N.R.C., later becoming chief editor. In 1984 she transferred to London and two years later covered the aftermath of the Chernobyl accident for Business Week and NucleonicsWeek. She wrote for Institutional Investor after leaving McGraw-Hill, but began writing again on nuclear topics for British or European publications such as GQ, the Index of Censorship, Readers Digest, The International Herald Tribune, and The Independent newspaper.
