Your goals in this chapter are to learn ■ The terminology of analysis of variance. Believe it or not, we have only one more common inferential procedure to learn and it is called the analysis of variance. This is the parametric procedure used in experi- ments involving more than two conditions. This chapter will show you (1) the general logic behind the analysis of variance, (2) how to perform this procedure for one common design, and (3) how to perform an additional analysis called post hoc comparisons. Each condition of the independent variable is also called a level, or a treatment, and differences in scores (and behavior) produced by the independent variable are a treatment effect. It is important to know about analysis of variance because it is the most common infer- ential statistical procedure used in experiments. Such complex designs are common because, first, the hypothe- ses of the study may require comparing more than two conditions of an independent variable. Second, researchers often add more conditions because, after all of the time and effort involved in creating two conditions, little more is needed to test additional conditions. We’ll create three conditions containing the unpowerful n of five participants each and provide them with the same easy ten math problems. However, we will tell participants in condition 1 that the problems are easy, in condition 2 that the problems are of medium difficulty, and in condition 3 that the problems are difficult.

These labels must be removed or defaced before disposal of the container in the unre- stricted areas. Caution signs are not required in rooms storing the sealed sources, pro- vided the radiation exposure at 1 foot (30cm) from the surface of the source reads less than 5mrem (50mSv)/hr. The annual limit of the occupational dose to the skin and other extrem- ities is the shallow-dose equivalent of 50rem (0. Depending on the license conditions, both internal and external doses have to be summed to comply with the limits. A licensee may authorize under planned special procedures an adult worker to receive additional dose in excess of the prescribed annual limits, provided no alternative procedure is available. The total dose from all planned procedures plus all doses in excess of the limits must not exceed the dose limit (5rem or 50mSv) in a given year, nor must it exceed five times the annual dose limits in the indi- vidual’s lifetime. Radiation Regulations and Protection The annual occupational dose limits for minors is 10% of the annual dose limits for adults. The dose limit to the fetus/embryo during the entire preg- nancy (gestation period) due to occupational exposure of a declared preg- nant woman is 0. Under this concept, techniques, equipment, and procedures are all critically evaluated. Principles of Radiation Protection Of the various types of radiation, the a-particle is most damaging because of its charge and great mass, followed in order by the b-particle and the g- ray. Heavier particles have shorter ranges and therefore deposit more energy per unit path length in the absorber, causing more damage. On the other hand, g-rays and x-rays have no charge or mass and therefore have a longer range in matter and cause relatively less damage in tissue. Knowl- edge of the type and energy of radiations is essential in understanding the principles of radiation protection. The cardinal principles of radiation protection from external sources are based on four factors: time, distance, shielding, and activity. Time The total radiation exposure to an individual is directly proportional to the time of exposure to the radiation source. Therefore, it is wise to spend no more time than necessary near radiation sources. Distance The intensity of a radiation source, and hence the radiation exposure, varies inversely as the square of the distance from the source to the point of expo- sure. It is recommended that an individual should keep as far away as prac- tically possible from the radiation source. Procedures and radiation areas should be designed so that individuals conducting the procedures or staying in or near the radiation areas receive only minimum exposure. The G values are derived from the number of g-ray and x-ray emissions from the radionuclide, their energies, and their mass absorption coefficients in air. The exposure rate X from an n-mCi radionuclide source at a distance d cm is given by a The G value of photon-emitting radionuclides can be calculated from the expres- sion G = 199ΣN Ei imi, where Ni is the fractional abundance of photons of energy Ei in MeV, and m is the mass absorption coefficient (cm2/g) of photons of energy E in air. Shielding Various high atomic number (Z) materials that absorb radiations can be used to provide radiation protection. Because the ranges of a- and b- particles are short in matter, the containers themselves act as shields for these radiations. Therefore, highly absorbing material should be used for shielding of g-emitting sources, although for economic reasons, lead is most commonly used for this purpose. The radiopharmaceuti- cal dosages for patients should be carried in shielded syringes.

A central wire and the chamber act as the elec- trodes and the current is measured by an electrometer generic aurogra 100 mg without a prescription erectile dysfunction herbs a natural treatment for ed. The detection effi- ciency of the ionization chambers for x-rays and g-rays is very low (<1%) and depends on the energy of these radiations generic aurogra 100 mg on line best erectile dysfunction doctors nyc. Ionization chambers are primarily used for measuring high-intensity radiation such as x-ray beams and high activity of radiopharmaceuticals. Cutie Pie meters, dose calibra- tors, and pocket dosimeters are the common ionization chambers used in nuclear medicine. Cutie Pie Survey Meter The Cutie Pie survey meter is made of an outer metallic cylindrical elec- trode and a central wire. It is primarily used to monitor the exposure at high radiation levels such as those from x-ray beams and 99Mo–99mTc generators. Dose Calibrator The dose calibrator is an ionization chamber and one of the most essential instruments in nuclear medicine for measuring the activity of radionuclides and radiopharmaceuticals. Since it measures the current produced by activ- ity, it does not have deadtime effects. It is a cylindrically shaped, sealed chamber with a central well and is filled with argon and traces of halogen at high pressure (~5–12 atmospheres). Because radiations of different types and energies produce different amounts of ionization (hence current), equal activities of different radionu- clides generate different quantities of current. Isotope selectors provided on the dose calibra- tor are the feedback resistors to compensate for the differences in ioniza- Ionization Chambers 75 Fig. In most dose calibrators, isotope selectors for common radionuclides are push-button type, whereas those for other radionuclides are set by a continuous dial. In the absence of specific recommendations, the earlier frequency and other related requirements of these calibration tests have been given as follows: 1. Gas-Filled Detectors Constancy Daily constancy check is performed by measuring a long-lived radioactiv- ity (e. Accuracy Accuracy of the dose calibrator is determined by measuring the activity of 137 57 at least two long-lived radionuclides (e. The measured activities are plotted against time on a semilog paper and the “best fit” line is drawn. If the deviation of any point from the line exceeds ±10%, the dose calibrator needs to be replaced, or a correction factor must be applied to the data in the nonlinear region. Shielding Method The advantage of this method is that it is less time-consuming and is easy to perform. The method utilizes a commercial kit, called Calicheck, that contains seven concentric tubes or “sleeves. When an activity source is measured by using first the inner sleeve, followed sequentially by increasingly thick sleeves, the data repre- sent the activities at different decay times. Calibration factors are calculated by dividing the innermost tube reading by each outer tube reading. For sub- sequent linearity tests, identical measurements are made using the sleeves, and each measurement is multiplied by the corresponding calibration factors. Each corrected sleeve reading should give an identical value, and the average of all values is calculated. If an individual reading exceeds the average value by ±10%, then the calibrator needs replacement, or a cor- rection factor needs to be applied. It should be noted that before the shielding method can be instituted, the linearity test must be first performed by the decay method for a new dose calibrator. Geiger–Müller Counters 77 Geometry Variations in sample volumes or in geometric configurations of the con- tainer can affect the accuracy of measurements in a dose calibrator, partic- ularly for low-energy radiations. Correction factors must be determined for these geometric variations and applied to the measured activities, if the error exceeds ±10%.
