Abstract
The present study aims to assess the seasonal variation in the accumulation of the isotopes {sup 238}U, {sup 235}U, {sup 234}U, {sup 232}Th, {sup 230}Th, {sup 228}Th, {sup 226}Ra, {sup 228}Ra and {sup 210}Pb in the cubera snapper fish from the coast of the state of Ceara (Brazil). The fish was caught in January (six specimens), June (eight) and September (seven). The uranium and thorium were analysed by electrodeposition, followed by alpha spectrometry. The isotopes of radium and lead were selectively co-precipitated and measured by gross alpha radiometry for {sup 226}Ra and gross beta radiometry for {sup 228}Ra and {sup 210}Pb. No seasonal variations could be observed neither for the uranium and thorium isotopes nor for the {sup 226}Ra isotope. For {sup 228}Ra, the activity concentration in February was equal to that of September, and both were higher than in June. For {sup 210}Pb, the situation was different: the month of February showed a lower activity concentration than in June, which in turn was lower than in September. (author)
