全国环境天然放射性水平数据库及其应用

NATIONAL DATABASE OF ENVIRONMENTAL NATURAL RADIOACTIVITY LEVEL AND ITS APPLICATION

本文介绍了全国（不包括台湾省）环境天然放射性水平数据库。该数据库由环境天然贯穿辐射水平、土壤中天然放射性核素含量和水体中天然放射性核素浓度３个分数据库所组成，包括２５３个子库以及多种应用软件。该数据库采用的机型为ＩＢＭＰＣ机及其兼容机，建库语言选用ｄＢＡＳＥ－Ⅲ，应用程序采用汉化ＢＡＳＩＣ编制。文中还对图象处理等应用软件和数据库建库后初期的应用情况作了简要的介绍。

This paper introduces the database of national survey of environmental naturalradioactivity level in China (except for Taiwan Province).The database consists of 3 parts :natural penetrating radiation level,natural radionuclide contents in soil and natural radio activity concentrations in water. It includes 253 sub-databases and various application softwares. This database runs on IBM PC and its compatible computers. The selected languageis dBASE-Ⅲ.The application programs were coded with Chinese BASIC. This paper brieflyintroduces prelimenary application of the database as well.
