- Alpha emitters of pCi/g amounts have been detected with a resolution of a few micrometers using a solid state track detector (cellulose nitrate) to map the activity in a coral sample from Bikini. Calibration methods used include: a Pu source of 0.15 ..mu..Ci in conjunction with polycarbonate and CaCO/sub 3/ absorbers of different thicknesses (2 to 30 micrometers), and a powdered coral sample which had been analyzed previously for alpha emitters by chemical methods in conjunction with an alpha spectrometer. 0.04 mm/sup 3/ can be measured routinely; lower concentrations can be determined but with less resolution. The alpha emitter concentration in CaCO/sub 3/ of the coral Favites virens from Bikini lagoon was analyzed by placing the detector directly on the slab sample for thirty days. Analyses of sections and thin sections of this coral slab cut perpendicular to one another, but parallel to the direction of coral growth, give very different concentrations and distributions of alpha emitters.
