Thallium

Thallium bromide-iodide crystals have also been used in infrared detectors. The addition of metals like thallium to glass can also reduce its melting point to as low as 150 degrees centigrade. As such low-melting point glasses do not shatter like normal glasses, they are particularly useful for the manufacture of electronic parts.

Radioactive lens. For a while thorium was added to lens glass to increase its index of refraction (which allows the lens to be thinner and lighter). It also increases its level of radioactivity, from zero to quite a bit: This rather small lens registers about 4000 counts per minute on my Geiger counter.

Thorium

Thorium may be three times more abundant on Earth than uranium, it is difficult to estimate, and can also be used in nuclear reactors. In addition, thorium and uranium deposits do not necessarily occur at the same places, thus countries with large potential uranium resources may well have very little thorium and vice-versa.
