Answer:. Justification is the answer. Dose limits are not applicable only recommened . Class Activity 4. While caring for his spouse Mr. Joseph got exposed to 2 mSv. As a member of the public with 1 mSv dose limit, he can not get any radiation dose this year. Answer:.
Justification is the answer.
Dose limits are not applicable only recommened.
While caring for his spouse Mr. Joseph got exposed to 2 mSv.
As a member of the public with 1 mSv dose limit, he can not get any radiation dose this year.
The average dose limit for a member of the public should not exceed 1 m Sv/y over 5y.
Regulations require that workers occupationally exposed to ionizing radiation wear devices called dosimeters so that accumulated doses can be monitored over a period of time.
There are several types but commonly used are Thermoluminescent dosimeters (TLDs)
Is necessary to measure the radiation doses received by the radiation workers in the course of their work to verify that these doses are within the recommended limits.
The medical physicist, RSO will identify individuals who have higher does and counsel them before their neglectfulness reaches serious proportions.
Methods of personal monitoring: film badges, TLD, pocket dosimeters.
Device used to measure and record the exposure of individuals to ionizing radiation outside the body (external dose).
Compared to photographic film dosimeters (film badges), TLD’s are more sensitive, reusable, often more nearly tissue-equivalent, cover a wider range of doses, allows us to measure deep and shallow doses, and most TLD materials are less subject to fading
Persons who are routinely exposed to radiation should wear (monitoring device).
Occasionally exposed workers need not to be monitored but removed from the exposure area/lead aprons when required.
Health care members who assist patients with radiographic procedures should be rotated.
TLD badge should be worn at the level of the waist or at the collar/neck region UNLESS pregnant.
Pregnant radiation workers should wear 2 TLD’s one on each location.
Radiologists/ Radiographers rarely wear ring badges; most often, they are worn by nuclear medicine technologists because of their exposure from handling radioisotopes.

My resident doctor has got 12 mSv in her last badge report as she was wearing the badge while getting her barium study. She wants off from radiation work.
What is medical physics:
The application of physics to medicine. It generally concerns physics as applied to medical imaging and radiotherapy, although a medical physicist may also work in many other areas of healthcare.
Supervise the preparation and handling, disposal of radionuclide.
