Rostrevor Beach Dose Rate
Last updated: 3 August 2010
Sediment Type: Shingles/Sand
| Gamma Dose Rate (uGy/hr) | 1998 | 1999 | 2000 | 2001 | 2002 | 2003 | 2004 | 2005 | 2006 | 2007 | 2008 | 2009 | 2010 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 0.120 | 0.116 | 0.117 | 0.119 | 0.124 | 0.127 | 0.128 | 0.139 | 0.115 | 0.117 | 0.103 | 0.119 | 0.106 |
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)
Rostrevor 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.
