Conceptual design of a wearable radiation detector alarm system: A review of the literature

The importance of a well-designed radiation detector has become evident in recent years. Researchers have begun a user-centred redesign process for a novel neutron detector instrument to improve comfort and usability of the device. In this design process it is important to consider the type of alarm system used to alert the responder in a non-startling, non-irritating manner. The purpose of this literature investigation was to explore past research in alarm design and determine the best type of alarm system for a wearable neutron detector. This paper considers the advantages and disadvantages of visual, auditory, tactile and multimodal alarms. The literature investigation found support for a visual + tactile alarm system for a wearable neutron detector. This article addresses the advantages and limitations of different alarm modalities, identifying strengths and weaknesses of uni-modal and multi-modal alarm systems. In addition, it also serves as a concise document of historical and contemporary research findings in the area of alarm design, which can be used as a design aid.
