Strange Glow: The Story of Radiation, by Timothy J. Jorgensen via Times Higher Education

From Mrs Roentgen’s ring to Fukushima fears: Richard Joyner on an informative popular history


Timothy Jorgensen’s Strange Glow offers a tour d’horizon of the history and physics of radiation and radioactivity (not necessarily the same thing) and presents risk-benefit analyses of some important applications. His background as an academic working in radiation medicine should make him an ideal person to do this. His book aims to be useful, while at the same time emphasising the human aspects of the story.

Many of the case studies he includes are well researched and mostly reassuring. Who now remembers the scare stories that mobile phones will fry our brains? Jorgensen shows that our complacency is not misplaced. Few people in the UK seem to have worried too much about eating tuna from the Pacific that may have been contaminated by radioactivity from the Fukushima nuclear catastrophe. Once again, the science shows that there is no cause for concern. Contamination of the home by the naturally occurring radioactive gas radon also need not worry most of us. The book’s section on diagnostic X-rays is very strong, with the discussion of mammography showing how difficult it can be to make good public health decisions.

However, Jorgensen is much less convincing on the risks of civil nuclear power. He considers the health consequences of the 1986 Chernobyl disaster, which he argues is the most lethal such event we are likely ever to see. Radioactivity from this catastrophe probably caused 38,800 cancers. Of these, 16,000 were thyroid cancer, which by implication we don’t need to worry too much about, as two-thirds will be cured. The remaining 22,800 apparently represent an increase of only 0.01 per cent in the expected cancer incidence in the affected population, so apparently no great worry there either. While I do not challenge Jorgensen’s statistics, here I find him complacent. He also ignores the risk presented by radioactive waste from atomic power plants, which will have to be stored safely for millennia. What havoc terrorists could cause with only a small amount of the tonnes of material already in storage.

As a sun worshipper, I looked to Strange Glow for information on skin cancer. Cancer Research UK says that there are about 200,000 cases of malignant melanoma a year worldwide, mostly brought on by exposure to the ultraviolet component of sunlight. Even though this number is higher than the total number of radiation-induced cancers that Jorgensen covers, he says that the effects of UV radiation are beyond his scope. This seems lazy but is perhaps just as well, as his description of the physics of UV is less than wholly accurate.

The human aspects that Jorgensen introduces to his account mostly work well, even if they have often been told before, as with Mrs Roentgen and her wedding ring. Others, such as the story of US engineer Carl Pillitteri, who survived the disaster at the Fukushima nuclear plant in Japan in 2011, add relatively little.
