摘要
The developing crisis at the Fukushima Daiichi nuclear power plant in the wake of the March 11 earthquake and tsunami has raised concerns over the health effects of radiation exposure:What is a'dangerous'level of radiation? How does radiation damage health? What are the consequences of acute and long-term low-dose radiation? Though radioactive steam has been released to reduce pressure within the plant's reactors and there has been additional radiation leakage from the three explosions at the plants, the resulting spikes in radiation levels have not been sustained.
