Tritium 3 H or T is the radioactive isotope of hydrogen that decays with a half life of Tritium is produced naturally in the upper atmosphere by interaction of nitrogen, and, to a lesser extent, oxygen with cosmic rays. After oxidation to HTO, it takes part in the natural water cycle. These tests which were mainly performed in the early s, led to an increase of tritium in precipitation over the continents of the northern hemisphere from roughly 5 TU to levels of the order of TU. One TU Tritium Unit means a tritium to hydrogen ratio of 10 Whereas the addition of bomb tritium to the environment practically eliminated the use of natural tritium as a tracer, it offered a new tool, i. If the tritium delivery as a function of time can be reconstructed, this penetration process can be used for quantitative studies of water movement through identification of the bomb peak in certain ground water bodies. However, there are natural limits to this method because tritium decay and dispersion make it increasingly difficult to identify the bomb peak in groundwater. These problems can be overcome by using tritium in combination with its decay product 3 He 3 He trit as first suggested by Tolstykhin and Kamensky and experimentally confirmed by Torgersen et al.

A few years ago, back when I was regularly trolling OKCupid for dates, I received a message from a potential paramour. He’d been scanning through the survey answers associated with my profile, and one response in particular gave him pause: when asked whether I’d consider dating someone with herpes, I’d responded no. It wasn’t some carefully considered stance on sexual transmitted infections, or grand statement about herpes.
For him, however, it was a potential deal breaker: As you’ve probably figured out by now, my suitor was a member of that vast group of sexually active adults who’ve been infected with herpes. The internet was supposed to be transformative for people with incurable, but highly preventable, STIs like herpes simplex virus HSV who wanted to date while being open about their status.
There’s no question that these sites which have even spawned their own Tinder-like apps are a fantastic demonstration of how innovative online dating platforms can be. But even as they bring together a number of people living with STIs, they don’t seem to do much to improve general education about living with herpes and other STIs. And as a result, people going online in search of connection and support often end up feeling stigmatized, isolated, and more alone than ever.
And in the beginning, that seemed to be the case. Hoping to improve her prospects, or at least connect with people in a similar position, Ellie turned to the internet. But despite the promise of community and support, she found that STI-focused dating sites just made her feel worse. And since these sites’ only criterion for joining was an STI diagnosis, members didn’t really have that much in common aside from their diagnosis, which many seemed obsessed by.
Ellie noted that “it was more of a group therapy site than a dating site. Nothing about it was sexy.

Studies of Cave Sediments pp Cite as. Carbonate speleothems that contain ppb-ppm levels of uranium can be dated by the U- U- Th and U- Pa disequilibrium techniques. Accurate ages are possible if the initial concentrations of Th and Pa are well constrained and if the system has remained closed to post-depositional exchange of uranium, thorium, and protactinium. For many speleothems, particularly those composed of nearly pure calcite, initial Th may be trivial.
Because Pa is more soluble than Th, Th is a poor analog for Pa. Therefore, initial Pa tends to be more significant than initial Th for young samples, although this problem becomes less significant or even insignificant with increasing age. Thermal ionization mass spectrometry TIMS and inductively coupled plasma mass spectrometry ICP-MS offer significant improvements in counting efficiency and sample throughput compared to traditional decay-counting techniques.
