Easy-to-use, handheld device helps to protect operations and reassure employees.
The Fluke 481 Radiation Detection Meter is a portable and practical means for discovering irradiated goods, and for helping remediate contaminant and safety issues while minimally affecting performances. Ideal for detecting irradiated goods, equipment, surfaces or environments in industrial settings, the 481 Radiation Meter helps ascertain worker safety and compliance to federal regulations.
Use of the Fluke 481 assures employees that radiation dangers are known, monitored and calculated for their security. Whenever radiation is found, a clear and quantifiable result provides handlers to comply with federal guidelines while avoiding unnecessary steps that could stop procedures, impact productivity or lead to missed revenue.
Innovation meets safety.
Goes everywhere contamination can go, from receiving dock to warehouse to shop floor, and scans vehicles, packages, or individuals.
Complete detection solution.
Detects the multiple types of ionizing radiation associated with contaminated goods.
High sensitivity for greater safety.
Works at a safe distance, before the user comes into close proximity and encounters unsafe radiation levels.
Simple two-button operation.
Allows new users to perform surveys with little training.
Measurable results for compliance with guidelines.
Delivers exact information about the extent of contamination, so safe perimeters may be set up.
The Fluke 481 is ideal for detecting irradiated goods, equipment, surfaces or environments in industrial settings, for ensuring worker safety and complying with federal regulations.
Q & A
What is the difference between the model 481 and 481-DESI?
Here is useful excerpt from the instruction manual
481: 0 to 5 mR/h, 0 to 50 mR/h, 0 to 500 mR/h, 0 to 5 R/h, 0 to 50 R/h
481-DE-SI: 0 to 50 μ Sv/h, 0 to 500 μ Sv/h, 0 to 5 mSv/h, 0 to 50 mSv/h, 0 to 500 mSv/h
481: 349 cc volume air ionization chamber; phenolic chamber wall 246 mg/cm2. Chamber window is composed of 6.6 mg/cm2 Mylar. A coating of graphite has been applied to the walls to make them conductive. The collection potential is -63 Volts. The Chamber is vented through the desiccant.
481-DESI: In order to achieve energy response consistent with measurements of H*(10) as required by ICRU report 47, aluminum has been added to the back wall, 38 % of the side wall area, and to the beta slide. With the Beta Shield open, the 481 can measure skin dose at H* (0.07), and Deep Dose H* (10) with the Beta shield closed.
Time measured from 10 % to 90 % of final value for a step increase/decrease in radiation rate such that a range change does not occur:
481: 0 to 5 mR/h, range: 8 seconds. 0 to 50 mR/h, range: 2.5 seconds. 0 to 500 mR/h range: 2 seconds. 0 to 5 R/h, range: 2 seconds. 0 to 50 R/h, range: 2 seconds.
481-DE-SI: 0 to 50 μ Sv/h, range: 8 seconds. 0 to 500 μ Sv/h, range: 2.5 seconds. 0 to 5 mSv/h, range: 2 seconds. 0 to 50 mSv/h, range: 2 seconds. 0 to 500 mSv/h range: 2 seconds NOTE: Instantaneous exposure rate is limited to 50 R/h (0.5 Sv/h), including but not limited to a pulsed field.
