Sediment Type: Mud
| Gamma Dose Rate (uGy/hr) | 1998 | 1999 | 2000 | 2001 | 2002 | 2003 | 2004 | 2005 | 2006 | 2007 | 2008 | 2009 | 2010 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 0.091 | 0.093 | 0.088 | 0.093 | 0.102 | 0.092 | 0.093 | 0.111 | 0.103 | 0.094 | 0.097 | 0.097 | 0.088 |
The average dose rates in air over intertidal sediments in the British Isles due to natural radioactivity are:
Sand 0.03 to 0.05 micrograys per hour (uGy/hr)
Mud 0.05 to 0.10 micrograys per hour (uGy/hr)
Narrow Water is an area which has granite sub layers and as such readings of up to 0.28 uGy/hr can be readily obtained inland from the coastline.
