Abstract
This invention relates to a device for monitoring exposure to influences, such as ionizing radiation, adverse to the human body. The device includes a support which carries material sensitive to the influence. The material is demarcated into a plurality of discrete zones each of which is processable individually by processing composition stored in a respective reservoir. Each reservoir is dischargeable individually to process its related zone. The sensitive material produces an indication visible externally of the device if the exposure to radiation has been greater than a predetermined threshold. The zones are processable at will in single succession.
