A couple feet of air will block alpha particles, so what might look safe from a gieger counter probe held at about shoulder-height by an adult could be very bad indeed for young-uns.Cybrluditehttps://www.blogger.com/profile/02222195374935367060noreply@blogger.comtag:blogger.com,1999:blog-12389938.post-31826316123415974142013-05-27T11:28:34.763-05:002013-05-27T11:28:34.763-05:00The only eye level referred to in weather lore is ...The only eye level referred to in weather lore is for growing corn, which should be as high as an elephant's eye when fully mature.<br /><br />I believe the eye level you have referred to is in NOAA's Instruction 10-1302 (Oct 4, 2005) for siting a weather observation station. 4 to 6 feet for the air intake of a remote sensor. Wind readings are supposed to be taken 33 feet (10 meters) off the ground.<br /><br />The science behind this air temperature height requirement is all about cold-air pooling, which, as you suggest, can be extreme in a very short air-column.Rivrdoghttp://rivrdog.typepad.comnoreply@blogger.com
