Limitations Interferences can still occur when different component sample elements produce similar gamma rays · The detection limit bulk matrix
Limitations • Interferences can still occur when different component sample elements produce similar gamma rays. • The detection limit • bulk matrix
Take sample to the rabbit system apparatus The rabbit system works much like the system used by banks at drive-through windows. A canister carries items back and forth between the customer and teller ⊙园 The sample is sent through the wall in a mini canister into the nuclear reactor located behind the wall Once inside the reactor the sample is irradiated with neutrons
Take sample to the rabbit system apparatus • The rabbit system works much like the system used by banks at drive-through windows. A canister carries items back and forth between the customer and teller. • The sample is sent through the wall in a mini canister into the nuclear reactor located behind the wall. • Once inside the reactor, the sample is irradiated with neutrons
After irradiation of the sample in the capsule, and before removing it from the reactor site it must be determined if the capsule is safe for transfer a geiger counter is used to assess whether the radioactive decay has reached low enough levels to be safe
• After irradiation of the sample in the capsule, and before removing it from the reactor site, it must be determined if the capsule is safe for transfer. A Geiger counter is used to assess whether the radioactive decay has reached low enough levels to be safe
The prepared sample and standard sample are placed in a detector one at a time The detector system counts and records gamma radiation emissions for a period of time Time varies, but is &EG:G ORT usually in the range of 5 minutes to an hour
The prepared sample and standard sample are placed in a “detector” one at a time. • The detector system counts and records gamma radiation emissions for a period of time. • Time varies, but is usually in the range of 5 minutes to an hour
