Dosimetry, personal monitoring film
Philosophy of Photography, 2011 The article focuses on radiation dosimetry, which made use of the photographic film known as Type 2 Monitoring Film (Kodak) to detect and measure harmful ionizing radiation. It explores the implications of the demise of this technology in relation to Henri Van Lier's critique of photographic indexicality in his paper "Towards a Philosophy Instigated by
