Every state has their own rules for monitoring radiations. Laws are always expanding and changing with exposure to radiation rises because of its medical use. This caused the increased regulation on radiation monitoring.
A radiation badge will be given to personnel who are working in a lab that uses machines that emit radiation. The requirement would be determined after the approval of a professional. A person should wear the badge when there is a chance of radiation exposure.
Dosimeters are not able to detect soft beta and alpha emitters that have an average energy not more than 100 keV. Professionals may need the use of extra monitoring badge if it is really required.
Every individual with a badge must be responsible for making sure that it is handled with great care. The professional would set a routine modification of dosimeters, exposure evaluation, and keep the radiation exposure records. Any big increase in the exposure record will be examined to know the possible cause and the suitable treatments.
Exchange of Dosimeters
A coordinator must be assigned to every group of dosimetry badge. It is the responsibility of each person to exchange the badge to their coordinator. Oftentimes, badges must be exchanged every month. A control badge is given with every dosimetry badge group. This control would know the radiation exposure background to the dosimetry badges shipment and would serve to examine any exposures during shipping.
Proper Use of Dosimeters
- The individual is the only one what must wear the badge. It shall not be loaned or use for area monitoring. There are other devices designed to monitor the radiation exposure of a certain area.
- When working with ionizing radiation, the badge must be worn in an area where exposure is great. Usually, it is on the collar. Other locations that are acceptable include the shirt pocket, sleeves, or the body trunk. Ring dosimeters must be worn when there is a chance of great radiation exposure to the arm. It is essential to wear the ring on the area that is exposed. Usually, it is on the index finger since it gets the largest exposure. To protect the ring from contamination, it must be worn under gloves.
- The dosimeter must be worn always when there is a chance of exposing yourself to a radiation while you are working. The dosimeter must not leave the facility. It must be stored in a radiation-free, safe area whenever you are not using it. The dosimeter must not be stored in hot or humid areas.
- The dosimeter packet should be put in the holder. This allows the radiation dosimetry interpretation. The plastic holder has filter sets and open window, which lets the professional to differentiate between the gamma and beta radiation. Also, it determines the radiation energy and the amount of exposure that has been recorded by the device. Return it to a professional for replacement if the holder is damaged or if the filters of the holder fall out.
