An apparatus and a method are described for the down-hole injection of radioactive tracer. The procedure relates to down-hole injection of radioactive bromine-82 and monitoring its progress through fractured structure to determine the nature thereof. An ampule containing the granular bromine is remotely crushed and water is repeatedly flushed through it to cleanse the instrument as well as inject the bromine into surrounding fractured strata. A sensor in a remote borehole reads progress of the radioactive material through the fractured structure. (6 claims.
