Description

In order to follow the movement of a beach fraction under the effect of the swell 17 kilograms of crushed radioactive glass (marked at 3 mc of Cr 51 per kilogram of glass) have been spread on a strip of 30 meters on 1 meter, at the level of wave breaking. By means of a portable scintillation detector, it was observed that, under the action of a slight easterly swell, this glass moved about 50 meters / hour towards the west. This process proved to be much simpler and faster than all the others methods used in this field.

Abstract (French)

Dans le but de suivre le deplacement d'une fraction de plage sous l'effet de la houle nous avons repandu 17 kilos de verre radioactif broye, marque a 3 mc de Cr 51 par kilo de verre, sur une bande de 30 metres sur 1 metre, au niveau du deferlement. Au moyen d'un detecteur portatif a scintillation, nous avons constate que, sous l'action d'une legere houle d'est, ce verre se deplacait a 50 metres/heure environ vers l'ouest. Ce procede s'est revele beaucoup plus simple et rapide que tous les autres utilises dans ce domaine.
