Environmental Radiation Surveillance Brookhaven National Laboratory Readings: Beginning 2009

This dataset measures the air, water, and fish near Brookhaven National Laboratory and other locations (background) around NYS to determine the normal levels of radioactivity and monitors the influence of human activities on these levels. The site numbers represent the location from which samples are collected. This dataset is not designed, or intended to monitor releases from discharge points at a specific facility (e.g., a stack). The facility operator performs this type of monitoring to meet the requirements of its licensing agency (e.g., a federal agency or the New York State Department of Environmental Conservation). A column has been added for values which can be graphed. Readings where a less than value is displayed show a value that is less than the detection limit of the measurement method and are essentially equivalent to 0. Variations in detection limit are due to variations in sample collection and measurement instrument performance.

本数据集旨在衡量位于布鲁克海文国家实验室及其他纽约州周边地区（背景环境）的空气、水体及鱼类中的放射性水平，以确定其正常值，并监测人类活动对放射性水平的影响。各站点编号代表样本采集的具体位置。本数据集的设计目的并非针对特定设施（如烟囱）排放点的排放进行监测。此类监测由设施运营商执行，以符合其许可机构（如联邦机构或纽约州环境保护局）的要求。此外，新增一列用于可绘制值的记录。当显示的数值小于某一值时，表示该数值低于测量方法的检测限，实质上等同于0。检测限的波动源于样本采集和测量仪器性能的差异。
