Abstract

Radiation-shielding is essential in fields involving storage and transport of radiation active material, such as medicine and nuclear engineering. The risk of radiation spill is a source of constant concern with its potential impact on local environment and life. Radiation spills that occur in laboratory are considered minor and containment of radiations in such cases using conventional techniques is not practical. Current practice involves using a suitable chemical absorbent, cleaning the spill region using agents and requires monitoring the spill region regularly for activity. Although this technique is effective in managing minor/laboratory grade spills, it requires careful application and constant monitoring before the area can be deemed safe for work. In this paper, we provide a detailed review of the radiation-shielding properties of polymer nanocomposites and their fabrication. The paper outlines radiation-shielding mechanisms, measurement of radiation attenuation, and factors that influence radiation attenuation. The review also compares analytical attenuation measurement methods against experimental methods. This review would be helpful in not only understanding the underlying energy transfer mechanism, but also aid in exploring polymer nano-composite materials as a viable green option for containing medium to low-level radiation spills.

掺杂纳米粒子的辐射屏蔽聚合物:综述
辐射屏蔽在涉及储存和运输辐射活性材料的领域(如医学和核工程)中至关重要。辐射泄漏的风险对当地环境和生命具有潜在影响,因此一直备受关注。实验室中发生的辐射泄漏被认为是轻微的,在这种情况下使用传统技术控制辐射是不切实际的。目前的做法是使用适当的化学吸收剂,用药剂清洗溢出区域,并要求定期监测溢出区域的活动。虽然这种技术在处理轻微/实验室级泄漏方面很有效,但在认为该区域可安全工作之前,需要谨慎使用和持续监测。在本文中,我们将详细介绍聚合物纳米复合材料的辐射屏蔽特性及其制造方法。本文概述了辐射屏蔽机制、辐射衰减测量以及影响辐射衰减的因素。该综述还将分析衰减测量方法与实验方法进行了比较。这篇综述不仅有助于了解基本的能量传递机制,还有助于探索聚合物纳米复合材料作为一种可行的绿色选择,用于控制中低水平的辐射泄漏。

期刊介绍: The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
