1. A method for determining an irradiation dose delivered in situ to an object, comprising the steps of:

  • irradiating at least one object with a radiation dose which is sufficient to sterilize the object;

    positioning a passively powered sensor proximate to the object such that it is held proximate thereto during said irradiating step, wherein said sensor has associated operational parameters, and wherein one or more of the operational parameters is configured to change responsive to said irradiating step, wherein the sensor is configured as a single-use sensor;

    wirelessly transmitting data associated with the change in the operational parameter in the sensor; and

    determining the radiation dose received by the object during said irradiating step based on the change in the operational parameter.
