As I wrote earlier, the cost wouldn't be directly proportional to the
increased or decreased frequency. For an example, if TLDs are worn
for a monthly frequency, and this is changed to a quarterly frequency
.. the cost will not drop down by 1/3 for the quarter. There is a
carrying cost for the TLD. If the TLD is out in the field for 3
month, or 6 months or as long as a year, it can not be used for
another individual until returned. Therefore, other inventory is
necessary to make up the variance in utilization potential. There is
also the amortization required for lifetime use, etc. As stated, the
cost could go up a bit for less use, but since the overall frequency
exchanges are less, the overall cost is going to be less.
Film dosimeters have less to do with the inventory issue, but there
are other considerations as well that demonstrate why wearing a film
4 times a year instead of 12 times a year, why the cost per period
isn't 1/3, as was suggested.
