The pipe is 10 m long, and the worker will need to be standing 50 cm from the pipe. A remote detector was used to take a reading of 1.5 R/hr at 3 m from the pipe. a) What is the dose rate at the work position? b) If the worker's dose limit is 30 rad, how long will he have to complete the work? Assume that there is no dose from approaching and leaving the work location.arrow_forward

- What is the dose in mSv for 1.5 mGy of α exposure?arrow_forwardYou are using a Cs-137 radiation source with an "activity" level of 5 μCi that emits primarily beta particles with energy 0.5120 MeV. Use the equation given to calculate the total beta-radiation exposure you would experience in 3 hours of lab work with this radioactive source. (H) is the equivalent dose rate in mrem/hr, (A) is the activity of the sample in Ci, (E) is the energy of the emitted radiation in eV, and (r) is the average distance from the source during the exposure in meters. To find the radius, use a reasonable distance - as if you were working with an experimental apparatus and radioactive sources in person during these three hours (how far, on average, would you be from the source during that time?). For comparison, you would be exposed to approximately 3.5 millirems if you were to fly from the east coast to the west coast of the US.arrow_forwardIn a Ussing chamber with Gramicidin channels inserted in the separating membrane.The left side has radioactively labeled K+ ions the right side has unlabeled ions K+, in equal concentrations (c1=c2).
