Dosimetry FAQs
What does the dosimeter do?
A radiation dosimeter measures the amount of high energy ionizing radiation a person has been exposed to during the wear period. These radiations include gamma radiation, x-radiation and high-energy beta radiation (such as P-32). The radiation dosimeter will not detect low energy beta emitters such as C-14 and H-3, therefore as a rule radiation workers using these isotopes will not be issued a dosimeter. The Dosimeter does not provide protection from radiation
How do I apply to get a dosimeter?
Complete RPR form1A. Please call Radiological Health at 581-6141.
When do I return my dosimeter?
Dosimeters are exchanged every month. If dosimeters are not received by the second working day of the month, please call Radiological Health at 581-6141.
Dosimeters must be exchanged promptly and returned to our department within 5 working days so we can mail them to the processor in a timely manner.
Dosimeters that arrive in our office after the 5th working day of the month they are due are considered to be late and will be assessed a $10 fee. Dosimeters returned more than 30 days late, or damaged, or misused in any way that invalidates the reading, are considered to be lost and will be assessed a $15 fee. The fees are billed to the department, which is responsible for obtaining reimbursement from the individual.
What are the dose limits for Radiation?
The occupational whole body dose limit is 5,000 millirems per year for radiation workers, effective dose equivalent. The dose limit to the extremities (hands, fingers, etc.) is 50,000 millirems per year.
What does the information on the badge mean?
Lost and Damaged Badges – Lost and damaged badges must be reported to the Department of Radiological Health as soon as possible @ 1-6141
Sharing badges – You should never use a badge other than your own, all badges are directly link to the individual’s dose of record.
Do not expose your badge intentionally.
Do not wear it when you receive medical or dental procedures.
