Remnants of sewer gas.

Going home after a housing co-op meeting, a friend offered to walk me to the bus stop. ‘‘I’m going to show you something’’ he said ‘‘and you won’t believe you’ve passed it so many times and never seen it before’’. As we rounded a corner he halted and I saw what I thought to be the base of a lamppost. Then I looked up, having to tilt my head back to see that this ‘lamp post’ was headless and at ...

Positron Annihilation in Noble Gas Mixtures

Hara and Massey [1] have investigated the annihilation of positrons in Ar-CO mixtures while the present author studied the behaviour of positrons in the noble gas mixtures (Ne + Ar) [2] and (He-)-Ar) [3]. It has been found that the annihilation decay constant, A, depends quite sensitively on the nature of the gas mixture. Our calculations [3] indicate that it will be quite interesting to explor...

Episode of toxic gas exposure in sewer workers.

OBJECTIVES Sewer workers are used to unpleasant smells, but may be required to investigate unusual ones. Twenty six men were involved in investigation of episodes of such a smell after neighbourhood complaints over several weeks. METHODS Workers exposed to the smell were investigated by clinical follow up, lung function tests, and measurement of pituitary function. RESULTS 14 of the 26 deve...
