Background Latent tuberculosis infection (LTBI) diagnosis in a country with a low tuberculosis burden is complicated. Since the prevalence of LTBI in second generation immigrants has not been well recognized, we conducted a cross-sectional study whic

The ^Ra, ^Th, ^U, and ^U dissolved in two ice samples removed from a 20-kg block of Yamato ice with tephra band K-26 were measured. One sample, 1.50kg of ice containing the band, had 252mg of particulates; the other sample, 1.78kg of ice outside the

The carbon-14(^C) terrestirial ages of four Yamato meteorites are measured and compared with the ^C terrestrial ages of eighteen meteorites from Victoria Land. The youngest Yamato meteorite, Y-75102,is (4.3±1.0)×(10)^3yr; the oldest, Y-74459,is (24

Gas is extracted from large (6–31 kg) Antarctic ice samples to obtain sufficient CO2 for14C measurements with small low-level proportional counters. The14C ages of Byrd core ice are in accord with glaciological estimates ranging from (2.2−1.1+1.4

Tritium is measured as a function of depth in a Surveyor 3 sample. The upper limit for solar-wind-implanted tritium gives a3H/1H limit for the solar wind of 1 × 10−11. The temperature release patterns of14C from lunar soils are measured. The14C re
