What do scientists use spectroscopy for? Research the uses of spectroscopy then describe one use and what we have learned. This week you have learned about nuclear reactions and the resulting radiation. In this discussion thread, you will be considering the health effects of radiation from nuclear reactions. Start by visiting the Health Effects web pages on the Environmental Protection Agency’s website located within the weekly readings.

Use the radiation dose calculator to find your estimated annual dose. Report your result and write a comment about it. Were you surprised? Does the result concern you? What were the major factors contributing to your estimated exposure? Are you going to change anything as a result of this finding?

Which factor should be checked when evaluating the effectiveness of an alpha-adrenergic blocker given to a client with benign prostatic hyperplasia (BPH)?

a. Creatinine clearance

b. Voiding pattern

c. Size of the prostate

d. Serum testosterone level

Explain the differences between confined and unconfined aquifers. (Illustration may help, again, you can not cut and paste the PowerPoint, but can interpret the PowerPoint and draw yourself, based on the power points are acceptable.

Antidepressant drugs work on neuronal synapses to ameliorate the symptoms of depression.  Based on your understanding of how presynaptic neurons communicate with postsynaptic neurons, how do these drugs work?

Describe a possible signal transduction mechanism involved in getting the message of an extracellular protein hormone to alter the metabolism of a target cell (you may be creative here but must have your response grounded in scientifically established signal transduction possibilities).
