Abstract
A method for monitoring a dose of penetrating radiation absorbed by an object, including the steps of providing the object with a device for absorbing penetrating radiation, including a storage phosphor for storing energy from the penetrating radiation; at predetermined intervals, coupling the storage phosphor to a source of stimulation light in such a way that the stimulation light impinges on the phosphor; activating the source of stimulation light so as to cause the storage phosphor to emit an amount of fluorescent light in proportion to an amount of stored energy; reading the amount of fluorescent light and converting it into an electric signal value; storing electric signal value(s) obtained at the predetermined intervals and processing them so as to evaluate a total amount of radiation absorbed by the object; comparing the total amount with a predefined threshold value for obtaining a difference value; and displaying the difference value on a decentralized display.
