Recently, several qigong doctors assert that there exists a 'qi field' among the qigong amateurs when they are doing qigong exercises or listening to a lecture given by a qigong doctor. Hence it is very interesting to detect the qi field by modern scientific means.

On Oct. 9, 1987, the famous qigong master Yan Xin was giving a lecture on qigong, Wang Yaolan, one of the authors, used 4 pieces of LiF thermoluminescence detector (TOLD), a kind of radiation dosimator, to try to detect the qi field. To our great surprise, the LiF TLD gave very strong responses to Yan Xin's qi field.

Dosage measured (mr)
. Control, 3 hours in
TOLD: Background of 3 hours during the same hall
TLD the lecture during film show . . _______________ ____________ ____________ ______________
7LiF(Mg,Ti) 3.9 51.0 9.5
6LiF(M,Ti) 3.5 62.6 5.8

There were two isotopes of Li, 7Li and 6Li. Mg and Ti were impurities added to LiF crystal. 7LiF TLD was sensitive to gamma-rays only and 6LiF TLD was sensitive both to gamma-rays and thermal neutrons. The measured dosage was calibrated to 60Cor rays.

Since the size of the LiF TLD used is very small (3 X 3 X 0.9 mm), you can put them anywhere at will, and the electromagnetic field has no influence on its registration power. It is very appropriate to use them for qi field distribution measurement. In October 1987, we measured the distribution of qi field during Yan Xin’s lecture for four times. All gave remarkable results. The following is a typical example:
Date and place: Oct. 21, 1987, Hong Qi Jie Assembly Hall
Duration of measurement: 3 and 1/2 hours
The qi fields of two other qigong doctors are also measured.


1. LiF TLD gives strong responses to the qi fields of Yan Xin and other two qigong doctors. It is expected that LiF TLD may be a convenient detector for the qi field distribution measurement.
2. The measurements give strong evidence that the qi field is an objective reality.
3. Many problems are left for further investigation, e. g. the components of the qi field detected by LiF TLD, the mechanism of registration of qi by LiF TLD, etc.
