参考解析
解析：本题考查的是对上下文之间意义关系的理解和对文章细节的把握。本题应该填与low-level radiation有关的内容。所以选项C是正确的。
本题考查的是对上下文之间意义关系的理解。此空前面一句介绍了澳大利亚拥有手机的现状，选项B的内容是对到2000年之前手机发展前景的预测，内容连贯。因此选B。
本题考查的是对上下文之间意义关系的理解。本题考查的是对上下文之间意义关系的理解和对文章细节的把握。这一段第一句说“许多微波发射塔建在人口稠密的居民区”。选项E的内容涉及微波发射塔的地点选择只考虑到地理位置而不顾及社区居民的安全。选项E扩展了第一句表达的信息。此外，选项E出现tower这个词，与第一句的tower 相呼应，也证明了选择的合理性。因此选E。
本题考查的是对上下文之间意义关系的理解。此空前一句说的是Robert Bell建议政府应该禁止在儿童比例高的地区（如学校操场、儿童医疗中心、居住小区等）的500 米半径范围内建造发射塔。选项A说明为什么要这样做，因此选A。
本题考查的是对上下文之间意义关系的理解和对文章细节的把握。此空后面一句说主要的电话公司出钱资助研究项目的问题，因此选项D是正确答案。
