The gamma-ray water curve is higher than the normal LTSF water curve because of ihe high-energy capture gamma ray from the lnconel window of the tank (see preceding discus- s ion). Since the medium contained almost as much hy- drogen and oxygen as does plain water and contained them in the same ratio, nogeometric correction was made in calculating the effective removal cross section, ur. The average uT for the range of 90 to 140 cm from the source was 0.750 barn. This com- pares with a value of 0.81 i 0.05 barn from an LTSF measurement behind a slab of graphite that contained 51.3 g/cm2 of carbon, which corresponds to PERIOD EMDlNG SEPTEMBER 70, 7954 10-3 L 1 ............... ! ....

Fast-Neutron Dose in Sugar Solution. the sugar-water solution at 145 cm, In order to observe the neutron attenuation in a medium removed from the source, the sugar-water solution is being placed in a 36-in.-long aluminum tank located 48.2 cm from the source. Thermal- neutron, fast-neutron, and gamma-ray measurements will be made in the tank. The measurements at the interface will indicate the difference in neutron age between water and the sugar solution for the more penetrating of the fission neutrons. 165
