Sepa report on 'Fukushima radiation' traced in Scotland
An environment watchdog has published a detailed report on radiation linked to Fukushima detected in Scotland.
Very low levels of iodine-131 were detected in air samples from across Scotland after the Japanese nuclear plant was crippled by an earthquake.
The Scottish Environment Protection Agency (Sepa) said the incident had not posed a significant risk to Scotland.
Iodine-131 believed to be from the plant was first detected in March.
According to Sepa's new report, it continued to be picked up from samples in some parts of Scotland until early May.
Samples from Ayrshire, Caithness, Dumfries and Galloway, Lothian and Shetland were checked for Iodine-131 (131I) as part of routine analysis of air quality.
In the report, Sepa said: "The concentrations of 131I detected around Scotland from the Fukushima nuclear incident in Japan did not pose a significant risk to human health and no special precautions were necessary.
"The concentrations detected were consistent with those found further afield, e.g across Europe, and demonstrate that the monitoring programme in Scotland is capable of detecting even trace levels of radioactive contamination present in the air."
A UK-wide report is expected later this year.
