Experiments will be performed usually in groups of two or four. You should choose a laboratory partner. For most laboratory periods there will be a brief discussion and explanation of the experiment to be performed. A quiz may also be given (probably will) at the beginning of each laboratory period covering last week's lab (or a lab in which no quiz was given). There MAY be some experiments or parts of experiments that cannot be adequately done as a group within the scheduled laboratory period. For these, you and your partner (or small group) will need to schedule a time during the week to do the work (when I am also available). The extra time spent outside of the scheduled laboratory will be compensated one way or another. In some instances, there will be weeks without labs, or small groups will alternate between weeks to perform labs due to insufficient numbers of instruments. Lab attendance is mandatory. See me if it is necessary for you to miss a lab for any reason. Labs can not be made up unless permission is obtained prior to the lab.
Each student is required to submit a report for each lab performed. Lab reports are due one week after
the experimental work is completed. They are to be handed in at the beginning of the next lab period.
If a student forgets to bring in the lab report to class, it may be submitted by the end of the day (4:00
PM MST) without penalty. The report should be submitted directly to me either electronically or on paper.
Late labs will be penalized one letter grade per 24 hour period late into my hands. This means if I leave
town for two days and you are only one day late your grade will STILL be reduced by two letter grades
unless submitted via email with a verifiable time stamp. Failure to submit one lab will result in
a "C" or lower grade for the class. Failure to submit two labs will result in FAILURE OF THIS CLASS.
Lab reports should be neat, organized, and concise. It is preferred that your reports be typed, except where impractical.
An ideal lab report should consist of:
You may work on the reports with your lab partners, and you MAY submit a single report with your lab partner BUT you will both get the same grade for the report and both names must appear on the report! Exams will NOT be given with lab partners, you must take all exams without any outside help whatsoever. For take home exams, you may feel free to use any reference materials that are available. If you choose to excerpt any information in your report, I expect you to reference it properly, especially if it is from the world wide web. Plagiarism will not be tolerated, and will be considered cheating. If you would like to reference more than a sentence or two, consider attaching the appropriate article or attaching the relevant information from the web to your report, rather than misleading anyone as to the authorship.
This class (and labs) requires students to seek references outside the textbook. The use of reference books such as ICRP 38, the CRC Handbook, The Radiological Health Handbook, and ICRP 23 will be necessary to complete the homework problems.
You will be REQUIRED to read assignments as well as the lab PRIOR to class and be prepared to conduct experiments at the start of class. A QUIZ may be held immediately upon the start of each class the covers the reading materials. Additional Pop Quizzes may be administered on an ad hoc basis and will be averaged into the pre-class quizzes. The quizzes and exams may be written, ORAL, PRATICAL or some combination of all three. All materials are cumulative, so exams, quizzes, labs and any other work will require that you recall and understand ALL previous materials.
Cheating will not be tolerated. The first time you are caught cheating you will get a ZERO for the task (exam, quiz, plagiarism on a paper or any other task). Integrity is the cornerstone of all health physics and any infraction, however slight, is not excusable for any reason. If another is found to be complicit in cheating, they too will receive a zero. If you are discovered to be cheating a second time you will receive a failing grade for the class. The Course Director will make the determination if a student has been cheating.
Summary Paper and Presentation
A summary paper and presentation is due at the end of class. It must be typed or sent electronically and the presentation will be for the entire class. The presentation will be 10 minutes long and cover the same material as specified for the paper. The paper will cover the following:
