The activity appears to be due to uranium and its daughters as determined by gamma spectroscopy.At first I thought the uranium was in the black vitreous glaze, but it actually appears to be distributed throughout the volume of the resistor material (also black in color).
The DOE’s Because of the wide dispersal of debris by the tests and continuing natural erosion processes, it was recognized at the time of decommissioning that there was a reasonable probability that some high-explosive and some potentially radioactive materials remained in the canyon.If you asked the same question of an educated European in AD 1900 you would have received a quite different answer.He would have answered that the Earth was ancient, that there had not been a Noachian flood, and that the species of life had not been fixed over the history of Earth.The activity is relatively mild–only about 300 CPM above background on a pancake GM detector.'Nuclear Package' Helps Farmers Increase Rice Yields and Income in Northern Malaysia.Thus, periodic surface surveys and searches were conducted in 1966, ’67, ’69, ’71, ’73, ’75, and ’76.
During such surveys a number of additional pieces of debris were located, with only a few of them being contaminated with “°Sr or including normal or depleted uranium.
The articles in my collection were probably all machine-painted, however.
The glow from these devices is feeble today, the result of radiation “burnout” of the zinc sulfide phosphor and NOT because the radium has decayed.
An integrated approach that includes a new rice variety, biofertilizer and plant growth promoter has made all the difference to rice farmer, Muhammad Helmi Mohd Noor and his neighbours in this northern Malaysian village.

I returned to Bayo Canyon in the company of Taylor Wilson on October 16, and discovered my first radioactive token from this locality—a short piece of shielded two-conductor cable that reads about 600 CPM on a 2″ pancake Geiger tube.
