內容簡介
本書給蘇聯1960年6月生效的電離輻射最大容許水平的新標準提出制訂的論據。
第一章闡述了人體受現存的天然的輻射源以及如醫用X線、核爆炸生成的裂變產物等人為輻射源的照射問題。
第二章扼要地介紹了國際輻射防護委員會的建議(МКРЗ-1959)的主要內容。
第三章論述了新標準ПДУ-1960的制訂根據,包括文獻來源。在制定ПДУ-1960時引用МКРЗ-1959的條件和範圍,新標準ПДУ-1960與МКРЗ-1959有些偏離的理由等。本章還將最大容許照射劑量與天然的和人為的電離輻射源的劑量作了比較。
在附錄中列出ПДУ-1960全文。
本書可供從事致電離輻射源工作的生物物理工作者、醫生、物理學工作者,工程技術人員的工作參考。也可供高等院校有關專業師生參考。
