The thallium content is low in environmental media such as water,soil,minerals and rocks,organisms and human bodies.

铊在水、土壤、矿物岩石、生物及人体等环境介质中的自然分布均较低，但矿山资源的开发利用等人为因素造成了铊对环境的严重污染。

Like Thallium SPECT, the PET scan has been very useful in differentiating tumor recurrence and radiation necrosis.

同铊标记SPECT一样，PET扫描对于区分肿瘤复发和放射性坏死十分有效。

The micro elements, such as galium, indium and thallium, present in the dust, are separated by means of solvent extractions.
