In 2010, the National Ignition Facility (NIF) is scheduled to achieve ignition. We propose radiochemistry of the fusion bum products as an attractive way to measure the amount of DT fuel that is mixed in with the surrounding ablator material. In addition, radiochemistry offers the possibility of measuring the temperature history of the DT fuel burn, the <{rho}r> of the fuel, and the neutron fluence of the 14 MeV, reaction-in-flight ('knock-on'), and low-energy neutrons. We can use prompt {beta} spectroscopy from the debris products and collection of the debris (for mass spectrometry) to make the radiochemical measurements. Radiochemistry thus offers the opportunity to make unique measurements, as well as provide crosschecks with results from other diagnostics for NIF ignition capsules. We will limit our discussion here to reactions involving 0.9 atom% copper-doped beryllium ablator capsules filled with DT and gold hohlraums.
