Discussion 1: If workers are exposed to 92 dBA for 2 hours, 90 dBA for 2 hours, and 85 dBA for 4 hours in the workplace, what percent of their daily noise dose would they receive using the hearing conservation limits? Briefly discuss the Occupational Safety and Health Administration (OSHA) requirements for evaluating this exposure related to a hearing conservation program, and explain the requirements for engineering controls and the use of hearing protection.

• Your answer must be a minimum of 75 words in length.

Discussion 2: Provide a definition and a brief explanation of each of the following meters, and detail how each meter might be used to evaluate physical hazards in the workplace: dynamometer, accelerometer, and goniometer.

• Your answer must be a minimum of 75 words in length.

Discussion 3: Describe the specific method you would use to evaluate a nurse's exposure to x-ray radiation while performing diagnostic tests at a clinic. Explain how your method works, why you would choose that method, and the benefits and weaknesses of that method, including how your method will affect the accuracy and precision of the data.

• Your answer must be a minimum of 75 words in length.

Discussion 4: Briefly discuss the difficulties associated with the evaluation of non-ionizing radiation sources. Summarize the methods that can be used for the evaluation of non-ionizing radiation in the workplace. Include a statement as to which method you believe would be the most reliable for evaluating infrared radiation exposures, and discuss how your method can affect the accuracy and precision of your data.
