This product has five colors to choose from (please note the color you need under the order after you place the order, or contact the customer service for the color you need):

Medical workers engaged in radiation work stay in various radiation environments for a long time because of work needs. Although some isolation measures can reduce the radiation dose received, long-term and low-dose accumulation can not be ignored. The International Commission on Radiological Protection (ICRU) proposal is the basis for personal dose monitoring. The main purpose of personal dose monitoring is to assess the radiation dose received by the individual staff member, thereby limiting the absorbed dose below the ICRP recommendation limit.

TLD-400 Personal thermoluminescent cumulative dosimeter, also called dose cards, dose pen, the detector has good energy response, high sensitivity, little affected by the environment, easy to use, can be measured Χ, γ, β, n other ray advantages. Widely used in personal cumulative dose of radiation detection, protection , radiology , radiation biology, geology, archeology and environmental protection, nuclear power plants, nuclear submarines, personal dose monitoring, environmental monitoring, occupational disease prevention and other areas of the field .

Specifications and uses:

(Don't has a thermoluminescence detector) Instructions for use: This product has no data to display directly. It only accumulates the radiation value of your environment. If it is medical, you can read the data (local CDC); if it is for industrial inspection Need to go to the local (Environmental Monitoring Agency) monitoring data. The monitoring period for individual doses is generally 3 months. Each person wears 2 doses of components and averages the measurements. Dosimeters can only be worn in the same position (left chest) as required during working hours. It is forbidden to artificially create “false” doses, such as “special handling” in the radiation field and under the ball. After each monitoring cycle is completed, dosimeters shall be sent back as required, and the monitoring unit shall perform dose measurement, analysis and preservation.

(Has a thermoluminescence detector) How to use: Anneal at 240°C ± 2°C for 10 minutes. Put the detector on the iron plate and place it flat. When the temperature of the annealing furnace rises to 240°C±2°C, place it in the oven. When the temperature rises again to 240°C±2°C, record the time and take it out after 10 minutes. Cooling on the metal plate, (The faster the cooling rate, the better, the temperature can not exceed 240 °C ± 2 °C, otherwise it will reduce the sensitivity). Place the cooled thermoluminescent chip in the dose box for use;

Test: Use the corresponding thermoluminescence dosimeter to calibrate the light source sensitivity after 30 minutes of power on, using the M2 program (ie: heating rate 15°C/S, first constant temperature 135°C/8S, second constant temperature 240°C/12S ), Measure after empty measurement 3 times or more.

[Note]: Don't touch the detector directly by hand. The dust-contaminated detector should be cleaned with alcohol. After the alcohol is evaporated, it should be dried and then used. Place it in a ventilated, dry place to avoid light exposure. Each batch of detectors cannot be used after Batch detectors are used together. Severely contaminated and annealed detectors are scrapped.
