1. An apparatus for determining the relative dose rate of a therapeutic radiation received by a patient, comprising:

  • (a) a probe assembly comprising;

    (i) at least one probe for placement near on internal to the patient, said probe havinga coating,an insertion end and an attaching end,an active portion within said probe constructed of a scintillation material, said scintillation material producing a signal upon being exposed to said therapeutic radiation;

    (ii) a probe connecting cable, having a first end and a second end,a signal analysis and readout unit connected to said probe with said probe connecting cable connected to a first electronic port of the signal analysis and readout unit;

    (iii) said attaching end attached to said first end;

    (iv) said second end being attached to the signal analysis and readout unit,said signal analysis and readout unit receiving signals from said scintillation material via said probe connecting cable, said signal analysis and readout unit having a signal detection and calculation means therein;

    wherein said signal and analysis unit determines said relative dose rate that is indicated on the signal analysis and readout unit, and is representative of the radiation dose received at the location of said probe.
