Abstract

Spallation produced radionuclides10Be,22Na and26Al and low energy neutron capture radionuclide60Co have been measured in several fragments of the Dhajala chondrite, their shielding depth in space having been established by measurement of cosmic ray track density. These data enable us to obtain depth profiles of production rates of these nuclides within the meteoroid body. These profiles are discussed in terms of their dependence on size of the meteoroid and variations of galactic cosmic ray fluxes in time and space. The slowing down density of neutrons of 0.1 neutrons/cm3 sec is determined near the centre of the Dhajala meteoroid based on60Co.
