Product Description

RTM-type I radon thorium measuring instrument

RTM-I radon thorium measuring instrument for portable "real-time" "continuous" measuring radon concentration/radon plasma thorium thorium and the total ∂ potential of the concentration of the multi-functional meter, for "active active" sampling structure, it has the advantages of typical, can be used for underground engineering, mine, tourism cave, nuclear facilities and associated uranium system and place the indoor environment radon measurement, health supervision and inspection and evaluation of radioactive, is a kind of looking for radon/thorium source, radon management, radiation safety evaluation and other necessary device, in line with the radiation effect committee radon monitoring and plasma thorium radon dose estimation (radiation dose in) of the application of requirements. This instrument can instant presented the results, simple operation, easy to carry, suitable for large-scale radon thorium level survey.

1. The radon thorium measuring instrument use conditions

A) the environment temperature:-10 ~ 45 ℃

B) the relative humidity: more than 95%

C) the power supply: 6 V battery, match charger, on a single battery charge can work continuously 6 hours; Can also be used AC220 / frequency 50 Hz.

2. Radon thorium measuring instrument main technical performances

A) lander: semiconductor detector, has small, fast response, of gamma not sensitive.

B) instrument at the end of this, more than 2 CPM. Sensitivity: 1.2 x 10-3 CPS/Bq/m3 (radon).

C) to 239 Pu alpha non-point source detection efficiency: 40% (2 π).

D) count capacity of 99999999; Measurement range: radon concentration 2-plasma/radon 1 x 106 Bq/m3, ∂ potential concentration: 1 x 10-8-10-2 J/m3.

E) the measuring time interval: way 1 (radon concentration measurement), way 3 (radon concentration measurement plasma thorium potential) are all 26 min, namely 26 to the results; For 1 ~ 2 way 100 share according to its level radon set timing radon concentration measurement thorium; The instrument has set for internal 26 min, and can meet the need of environment protection environmental measuring.

F) the instrument a high degree of automation, may change the Settings, automatic shows, instant presented the results, set "output" function keys, internal can store 100 history measurement results.

G) miniature sampling pump: 1 L/min (internal).

H) size and weight: 245 * 245 * 255, 5 Kg.
