Almost Done!

June 24, 2007

Here it is,  the last class coming up.  I wanted to pass on how much I’ve enjoyed teaching this class.  I’ve learned a great deal from all of you.  I appreciate all your feedback.  My goal is to improve the course for the next time.  

This last class, we will have a short review and discussion.  I want to ensure that we’re covered and refreshed the material.  I’ll ask each of you to complete a questionnaire on the course.   I value each of your comments.   I’ll have the final examination posted very shortly.  Please read it carefully, answer the questions as in the instructions.  Don’t ‘fluff’ the answers.  If possible,  please turn in the test by the 13/14 July and no later than the following Wednesday – the 18th.  I need time to grade them and provide them to UCM.   Thanks!

So,  I know that we couldn’t cover all aspects of Industrial Hygiene.  There are just too many to compress into a single class.  But,  the door is wide open for your exploration.  There’s no reason you couldn’t go on an adventure into IH yourself.    Be the Mongoose!

See you on the 13th.

Hazardous Energy and Electricity: Greater Risk of Cancers for Certain Railway Workers

6/13/2007
Printer-Friendly Format

A new study published in the Journal of Occupational and Environmental Medicine suggests that some railway workers are at increased risk for contracting certain cancers. Engine drivers spend long hours exposed to high levels of extremely low-frequency magnetic fields (EMFs). EMFs surround common electrical devices such as computers and power lines, and they also occur in nature. But so far, normal exposure to EMFs has proven to be safe.

A recent study conducted at the University of Switzerland at Berne looked at 20,000 railway workers to see if there was a relationship between the excessive exposure from their jobs and their cancer rates. While most railway employees did not show a direct relationship between exposure levels and rates of cancer, railway drivers (whose jobs result in EMF exposure levels up to 20 times greater than those received by other railway employees) showed increased rates of myeloid leukemia and Hodgkins’ disease. The researchers recommend that equipment be redesigned to minimize exposure.
