The present method enables an RFID repeater to be used in conjunction with an RFID tag to allow data in the RFID tag to be read using wireless packet switched technologies. The disposable probe assembly includes a breakaway collar which, when twisted away, activates a finger lock element which provides release of the disposable probe assembly from the reusable probe assembly. A closed-loop control system is employed to control operation of the multi-mode transmission accounting for all the presently applied clutches. The handoff may also be initiated by the UMTS, the selection being power-based. 01 to 1% by weight of a perfluorovinylether unit represented by the formula :\u2014CF2\u2014CF\u2014\u2003\u2003wherein X represents a perfluoroalkyl group having 1 to 6 carbon atoms or a perfluoroalkoxyalkyl group having 2 to 9 carbon atoms, the modified polytetrafluoroethylene having a heat of crystallization of 18 to 25Jg measured by a differential scanning calorimeter. In the method of measuring the dose of a radiation applied to fluid very small substances, the radiation dosimeter for fluid very small substances is used.
