During the 1980s and 1990s I contributed regularly to BBC Radio 4's weekly magazine programme Science Now.

From 1982 I researched, wrote and presented a number of radio documentaries and series, including No Science Please - We're British and This Little Piggy (a six-part series for parents about the under-5s). My 1988 series The Seven Ages of Health, investigating local and regional initiatives to promote health and prevent disease in Britain, won a Glaxo Science Writers' Prize.

More recent work for radio includes the historical series Cold War: Hot Science (1996), the six-part series of Blue Skies (2000), on the theme of images in science, and the documentary on music and memory Here’s One I Prepared Earlier (2004) on Radio 3; Hearing Colours, Eating Sounds (two-part documentary, 2002) on the topic of synaesthesia, Lifeblood (two-part documentary, 2003) and Wired for Life (2 part documentary, 2004) for Radio 4; and Restoration Science (four-part documentary, 2004) for BBC World Service.

On 24 November 2007 Robyn Williams of Australian Broadcasting's The Science Show conducted a long interview with me about Max Perutz The Science Show
