    Suppose further that room and instrument background counts are negligible or have been subtracted from N 1 and N 2.

    Then the number of counts from 99m Tc in window 1 [ N 1 99m Tc ] can be calculated from. Crosstalk from 51 Cr into the 99m Tc window must be corrected for, using methods described in the text.

    Equations and permit calculation of the number of counts that would be recorded in the photopeak window for each radionuclide in the absence of crosstalk interference from the other radionuclide.

    These equations can be used for other combinations of radionuclides and window settings with appropriate changes in symbols.

    For greatest precision, the ratios R 12 and R 21 should be determined to a high degree of statistical precision e.

    Generally, the technique is not reliable for the in vivo measurements described in Section F, because of varying amounts of crosstalk caused by Compton scattering within body tissue.

    A mixed sample containing 99m Tc and 51 Cr provides 18, counts in the 99m Tc window and counts in the 51 Cr window. A sample containing 51 Cr alone gives 25, counts in the 51 Cr window and 15, crosstalk counts in the 99m Tc window, whereas a sample containing 99m Tc alone gives 20, counts in the 99m Tc window and crosstalk counts in the 51 Cr window.

    What are the counts due to each radionuclide in their respective photopeak windows? Assume that background counts are negligible.

    The crosstalk interference factors are, for 51 Cr crosstalk in the 99m Tc window. Therefore the counts in the 99m Tc window from 99m Tc in the mixed sample are Equation If higher levels of activity are employed, serious dead time problems can be encountered see Chapter 11, Section C.

    Samples with high counting rates require short counting times and provide good statistical precision with little interference from normal background radiation.

    If only a few samples must be counted, they can be counted quickly and conveniently using manual techniques; however, with long counting times or large numbers of samples, the counting procedures become time consuming and cumbersome.

    Systems with automated sample changers have been developed to alleviate this problem Fig. Typically, these systems can accommodate or more samples, and each sample is loaded automatically into the counter in a sequential manner.

    Hundreds of samples can be loaded and measured in a single run. This system also incorporates a multichannel analyzer for spectral analysis.

    As shown in Figure , the sample hole passes through the entire length of the NaI Tl crystal, and the PM tube is connected to the side of the scintillator.

    A key advantage of the through-hole detector is that samples can be automatically positioned at the center of the NaI Tl crystal, irrespective of sample volume.

    This results in the highest detection efficiency and minimizes efficiency changes with volume. Figure shows the smaller changes in efficiency with volume for a through-hole versus a well-type counter for 59 Fe.

    Placement of the sample can be automatically adjusted to center the sample volume in the detector. The efficiency of the through-hole detector shows less variation with sample volume because the sample can be centered in the detector.

    Adapted from Guide to Modern Gamma Counting. Systems with automated sample changers not only save time but also allow samples to be counted repeatedly to detect variations caused by malfunction of the detector or electronic equipment or changes in background counting rates.

    Background counting rates can be recorded automatically by alternating sample and blank counting vials. In these systems, counting vials loaded into a tray or carriage are selected automatically and placed sequentially in the NaI Tl well counter.

    Measurements are taken for a preset time or a preset number of counts selected by the user. The well counter usually is shielded with 5 to 7.

    Even some small animals have been shown to have such a sense. The mother was diligent in laying an extra egg every day to make up for the missing egg.

    Some research has shown that hens can be trained to distinguish between even and odd numbers of pieces of food.

    However, our conjectures about how and when these ideas emerged among humans are simply that; educated guesses based on our own assumptions of what might or could have been.

    As societies and humankind evolved, simply having a sense of more or less, even or odd, etc. Certainly it was important for them to know if the flock of sheep or other possessed animals were increasing or decreasing in size.

    This method uses the idea of one to one correspondence. In a one to one correspondence, items that are being counted are uniquely linked with some counting tool.

    In the picture to the right, you see each stick corresponding to one horse. By examining the collection of sticks in hand one knows how many animals should be present.

    You can imagine the usefulness of such a system, at least for smaller numbers of items to keep track of. Of course, in our modern system, we have replaced the sticks with more abstract objects.

    These modern symbols took many centuries to emerge. In , Karl Absolom discovered a wolf bone that goes back possibly 30, years. It is believed to be a counting device.

    The markings on rows a and b each add up to Row b contains the prime numbers between 10 and Row c seems to illustrate for the method of doubling and multiplication used by the Egyptians.

    It is believed that this may also represent a lunar phase counter. As methods for counting developed, and as language progressed as well, it is natural to expect that spoken words for numbers would appear.

    Unfortunately, the developments of these words, especially those corresponding to the numbers from one through ten, are not easy to trace. Past ten, however, we do see some patterns:.

    Of course, the symbols used simple notches certainly did not leave a lot of flexibility for communicating a wide variety of ideas or information.

    And these are just a few of the many possibilities. These are just a few examples of early methods of counting and simple symbols for representing numbers.

    Extensive books, articles and research have been done on this topic and could provide enough information to fill this entire course if we allowed it to.

    The range and diversity of creative thought that has been used in the past to describe numbers and to count objects and people is staggering.

    There is generally a lack of books and research material concerning the historical foundations of the Americas. The reasons for this may be twofold: first, it is thought that there was a lack of specialized mathematics in the American regions; second, many of the secrets of ancient mathematics in the Americas have been closely guarded.

    Two researchers, Leland Locke and Erland Nordenskiold, have carried out research that has attempted to discover what mathematical knowledge was known by the Incas and how they used the Peruvian quipu, a counting system using cords and knots, in their mathematics.

    These researchers have come to certain beliefs about the quipu that we will summarize here. It should be noted that the Incas did not have a complicated system of computation.

    Where other peoples in the regions, such as the Mayans, were doing computations related to their rituals and calendars, the Incas seem to have been more concerned with the simpler task of record-keeping.

    We will describe them in more detail in a moment. However, they first often needed to do computations whose results would be recorded on quipu. To do these computations, they would sometimes use a counting board constructed with a slab of stone.

    In the slab were cut rectangular and square compartments so that an octagonal eight-sided region was left in the middle. Two opposite corner rectangles were raised.

    Another two sections were mounted on the original surface of the slab so that there were actually three levels available. In the figure shown, the darkest shaded corner regions represent the highest, third level.

    The lighter shaded regions surrounding the corners are the second highest levels, while the clear white rectangles are the compartments cut into the stone slab.

    Pebbles were used to keep accounts and their positions within the various levels and compartments gave totals. For example, a pebble in a smaller white compartment represented one unit.

    Note that there are 12 such squares around the outer edge of the figure. If a pebble was put into one of the two white larger, rectangular compartments, its value was doubled.

    When a pebble was put in the octagonal region in the middle of the slab, its value was tripled. If a pebble was placed on the second shaded level, its value was multiplied by six.

    And finally, if a pebble was found on one of the two highest corner levels, its value was multiplied by twelve. Different objects could be counted at the same time by representing different objects by different colored pebbles.

    Suppose you have the following counting board with two different kind of pebbles places as illustrated. Let the solid black pebble represent a dog and the striped pebble represent a cat.

    How many dogs are being represented? Watch this short video lesson about Inca counting boards. You will find that this is a review of concepts presented here about counting boards.

    This kind of board was good for doing quick computations, but it did not provide a good way to keep a permanent recording of quantities or computations.

    For this purpose, they used the quipu. The quipu is a collection of cords with knots in them. These cords and knots are carefully arranged so that the position and type of cord or knot gives specific information on how to decipher the cord.

    A quipu is made up of a main cord which has other cords branches tied to it. With base 10 being a counting system based on fingers, if you bring in the toes, then you can have a base system.

    The fingers are 1 through 5, and then counting goes up the arm, with the wrist 6, mid-forearm 7, up the arm to the neck at 11, an ear at 12, an eye at 13, the nose at 14, and back down the other side of the head, neck, and arm to the fingers on the other hand being 23 through Vestiges of other counting systems survive too.

    The Babylonian base 60 appears in the number of minutes in an hour and seconds in a minute. Base 12 appears in measurement; 12 inches in a foot , 12 months in a year, etc.
