## Abstract

A method includes detecting currently existing dose rates while a worker is performing an operation within a Radiologically Controlled Area (RCA) and visually outputting to the worker a dosage rate map of ionizing radiation within the RCA. The visual output can be visually depicted on a display that is worn by the worker during the operation and that is situated in proximity to the worker's eye. Another method of visually outputting to a worker a number of visual indicia that are representative of a number of parameters of an operation performed inside or outside the RCA includes periodically receiving a number of inputs from a number of detectors, employing the inputs to determine values for the parameters, and depicting the number of visible indicia on an electronic visual display that is situated on the worker and that is disposed proximate an eye of the worker.

## Claims

### Claim 1

A method of outputting a set of data pertaining to a number of dose rates within a Radiologically Controlled Area (RCA) during an operation wherein a worker is situated within an interior region of the RCA, the method comprising:
detecting dosimeter data for each dosimeter of a number of dosimeters situated within the RCA by:
periodically detecting from the dosimeter a measured dose rate that is representative of a rate at which the dosimeter is exposed to ionizing radiation, and
detecting a position within the RCA where the dosimeter is situated when the measured dose rate is detected;
determining a number of most current dose rates each being at a corresponding location from among a number of locations within the RCA based at least in part upon the dosimeter data; and
outputting a set of continually updated data based at least in part upon the number of most current dose rates.

### Claim 2 (depends on 1)

The method of claim 1 wherein each most current dose rate of the number of most current dose rates is representative of a rate at which an object situated at the corresponding location would be exposed to ionizing radiation.

### Claim 3 (depends on 1)

The method of claim 1 wherein the detecting of dosimeter data for each dosimeter of the number of dosimeters further comprises:
storing in a storage as a part of a data record a data entry that comprises at least the measured dose rate and the position; and
employing the data record in the determining of the number of most current dose rates.

### Claim 4 (depends on 3)

The method of claim 3, further comprising storing as a portion of the data entry a corresponding time when the measured dose rate was detected, the corresponding time being at least one of prior to the operation and during the operation.

### Claim 5 (depends on 1)

The method of claim 1 wherein the outputting comprises visually outputting at least a portion of the set of continually updated data.

### Claim 6 (depends on 5)

The method of claim 5 wherein the visually outputting comprises outputting on a visual display a visible output that includes a number of visual objects, at least some of visual objects of the number of visual objects each being representative, at least in part, of a most current dose rate of the number of most current dose rates and the corresponding location.

### Claim 7 (depends on 6)

The method of claim 6, further comprising visually displaying as a part of the visible output a dosage rate map that comprises a first visual object of the number of visual objects that is representative of at least a portion of the RCA and that further comprises a number of second visual objects of the number of visual objects that each include at least one indicium that is representative, at least in part, of a most current dose rate of the number of most current dose rates and the corresponding location.

### Claim 8 (depends on 7)

The method of claim 7 wherein the number of second visual objects are situated with respect to the first visual object in a fashion that is representative of the arrangement of the number of locations within the RCA.

### Claim 9 (depends on 8)

The method of claim 8 wherein at least some of the second visual objects of the number of second visual objects each include as the at least one indicium a visual element that includes at least a first numeral that is representative of the most current dose rate.

### Claim 10 (depends on 9)

The method of claim 9 wherein a first subset of the at least some of the second visual objects each include a second indicium in the form of a first color that is representative of the most current dose rate, and wherein a second subset of the at least some of the second visual objects each include another second indicium in the form of a second color that is representative of the most current dose rate, the first color and the second color being different from one another and being representative of the most current dose rates in the first subset being different from the most current dose rates in the second subset.

### Claim 11 (depends on 8)

The method of claim 8 wherein at least some of the second visual objects of the number of second visual objects each include as the at least one indicium a visual element that includes a color that is representative of the most current dose rate.

### Claim 12 (depends on 5)

The method of claim 5 wherein the visually outputting comprises outputting on a visual display that is situated on the worker and is disposed proximate an eye of the worker a visible output that includes a number of visual objects, at least some of visual objects of the number of visual objects each being representative, at least in part, of a most current dose rate of the number of most current dose rates and the corresponding location.

### Claim 13 (depends on 1)

The method of claim 1, further comprising situating a dosimeter of the number of dosimeters in proximity to the worker to enable the dosimeter to move with the worker within the RCA.

### Claim 14 (depends on 1)

The method of claim 1, further comprising:
situating a dosimeter of the number of dosimeters on a movable platform that is movable about the RCA; and
moving the movable platform about the RCA to cause the dosimeter to move with the movable platform within the RCA.
