Rock aggregates are major ingredient of concrete used for shielding against ionising radiation generated during the operation of nuclear particle accelerators. Their analysis for trace elements which may lead to neutron activation products during prolonged operation becomes important. Proper selection of ingredients helps in minimizing the radioactive concrete waste requiring disposal at the time of decommissioning.This work involves the collection of 42 samples of seven broad types of rock aggregates and their assessment for natural radioactivity ( 226 Ra, 232 Th and 40 K), lithium and other trace elements that may lead to the formation of gamma emitting, long lived neutron activation products.
