This dosimeter provides real-time, instant information about radiation dose and dose rate.
A thermoluminescent dosimeter, or TLD, is a type of radiation dosimeter. A TLD measures ionizing radiation exposure by measuring the amount of visible light emitted from a crystal in the detector when the crystal is heated. The amount of light emitted is dependent upon the radiation exposure.
DTN stands for “Dosimeter Transaction Number” and is the seven digit, alphanumeric data printed on the front and back labels of each dosimeter. On the ring label, it is the six digit numeric data printed above the barcode. DTNs are unique for every dosimeter issued.
DSN stands for “Dosimeter Serial Number” and is printed beneath the barcode on every dosimeter and ring used by RDC. DSNs are not visible to the customer, but are scanned during assembly the assembly process, along with the DTNs, on their corresponding badge/ring labels. DSNs indicate the completion of the build process and that a dosimeter/ring has been issued.
The control badge is used to monitor non-occupational energies that the personnel badge was exposed to. This includes background and other sources of radiation not a part of the workplace radiation exposure. The control badge should be stored in a location away from the radiation source at your facility. Break rooms or receptionist areas are good examples of areas that are typically appropriate.
RDC’s badges do read below 10 mrem. We do not report dose below 10 mrem due to the potential of false results at these very low levels of exposure and the 10mrem threshold is the level required to be reported by the regulations governing this industry.
If you are monitoring occupational dose to employees in a room where the source is located, or a room near a source that radiation could potentially reach, an Area Monitor should be placed at the highest exposure level where an employee may be working. Never place an Area Monitor on top of a source, or in a high radiation area that would not reflect occupational exposure.
It is the responsibility of the company to prove that the public is not being exposed to more than 100 mrem/year from outside a room/building. If you are monitoring potential exposure to the public, the Area Monitor should be placed on the outside of the room at the highest exposure level where employees/people are walking, sitting or may have access.
A Fetal badge should be worn directly over the Fetal area in order to receive the most accurate reading on my Dose Report.
No, only one badge is required for the fetal area.
No. RDC’s badges are meant for use by one individual at a time so that the dose associated with that badge is assigned to that one individual’s records. If multiple individuals use one badge, it is not possible to separate out what dose belongs to each individual therefore making the reading invalid for the intended user of the badge.
Commitment to the Industry At RDC, we pride ourselves in our longevity and our commitment to service. In business since the dawn of the industry, RDC understands the threats ionizing radiation pose in the workplace, and how important your service is to you and your employees. In-house experts are available during our business hours to assist in an un-biased, knowledgeable manner. We are accredited to NVLAP and registered to ISO 9001:2008.
Commitment to Our Customers RDC is privately owned with many employees who have been with us for over 20 years. The people working on your account are familiar with the technology, familiar with the industry and most importantly, familiar with you. We have intentionally well staffed customer care and sales departments so that when you call us, you can get a real person instead of a phone tree. We value our customers and wish to see them treated as we would want to be treated.
Here’s what you can expect from RDC:
-Access to RDC’s free online management tool "MyRadCare"
-Ability to download reports / invoices
-Each badge can be color-coded and / or identified by department
-NO maintenance fees
-NO fees to add, delete or make changes to wearers
-NO fees to add multiple groups or to transfer wearers between groups
-NO fees to ship badges in the middle of a wear cycle
-NO fees for duplicate copies of reports when generated through MyRadCare
-NO fees for termination reports when generated through MyRadCare
-NO fees for NRC-5 forms when generated through MyRadCare
-NO fees for email notifications alerting customers to unreturned badges
-NO fees to make payments online
RDC will not charge you hidden fees or extra surcharges. When you receive a price from RDC, that is what you will see on your bill (provided you didn't lose or damage a badge). Other provider's in the marketplace often add in additional charges for these requests making your total cost of service much higher than advertised. So even with a low badge price, when you add in all the additional charges, RDC comes out the clear winner.
Commitment to Innovation Radiation Detection Company maintains state of the art lab facilities to ensure we can provide our customers with the highest quality of service. We have invested heavily in our online systems to provide our customers immediate electronic access to their records.
RDC also provides TLD & TASL systems to private labs, governmental agencies, and healthcare providers around the world. We are experts in the systems, lab implementations and maintenance.
RDC offers monthly, bi-monthly, quarterly and semi-annual exchange frequencies.
If you lose a badge, you will need to notify RDC and order a replacement badge. Your account will be charged $10 for each lost badge. If the badge is found and returned within 60 days of the end of the most recent wear period, a $5 credit will be issued to your account.
RDC’s customers are best served when we understand the sources around which you work. A completed Radiation Source Sheet helps us determine the accurate response of our dosimeters. An improperly exposed badge can be more easily identified and errors can corrected by making minor adjustments that ensure the most accurate dose readings possible.
Radiation Source Sheets are also used to calculate dose from our ring dosimeters. A ring dosimeter contains one phosphor, unlike our typical TLD badge, which contains four separate phosphors and filtration that can discriminate different energies. This makes it impossible to automatically determine what type of radiation a ring has been exposed and this discrimination of energies is what determines the type of radiation to which the badge has been exposed.
During the setup of your account, a review of your sources allows us to set the type of radiation the ring will be exposed to. This insures the proper correction values are applied during the calculation process. While we can report dose from our ring dosimeters without the proper correction factors, the readings may not be as accurate.
Postage prices for US Postal Service First-Class Mail Parcel service can be found in MyRadCare under the Help Tab. Padded envelopes and boxes are considered packages/parcels, not letters or large envelopes, and require additional postage. Please return all badges in a padded envelope or box only.
Use the box provided by RDC in which the Sealed Source Wipe Test Analysis kit was shipped. When returning swab samples, place contents inside the box in a manner that will avoid damages during shipping.
