The Chola College of Engineering pioneered the use of gamma rays to examine large trees

Newswise – Lecturers on the Faculty of Nuclear Expertise, Faculty of Engineering, Chulalongkorn College have developed a particular tree-scanning system to find out tree trunk density and clearance to stop tree fall accidents and likewise as a approach to protect giant bushes in city areas.

Massive bushes standing tall for years with branches unfold out to offer shade could look wholesome and durable, but one can not know if their trunks may very well be hole. This may trigger tree fall accidents, injure pedestrians, and even trigger loss of life like what occurred 5 years in the past when the royal poinciana (flame tree) fell on the Chola sanctuary.

This deadly accident is what impressed Affiliate Professor Nares Chankow and Dr. Manusavee Lohvithee, lecturers at Chula’s Division of Nuclear Expertise, Faculty of Engineering, to develop a tree-scanning system utilizing gamma rays to find out the well being of bushes by way of stem density making it the primary and solely such try right here in Thailand.

In line with Assoc. Professor Nares, “Gamma rays can penetrate tree trunks like x-rays of our our bodies in a hospital. This process will assist decide the well being of the tree – whether or not its inside is wholesome, has turn into hole because of decay, or has been devoured by termites and termites. Different sorts of rays also can carry out this process, however X-rays require using a generator which will require electrical currents and is due to this fact not very appropriate to be used.”

Utilizing gamma rays for wholesome bushes and folks’s security

assistant. Professor Nares additional defined that the gamma ray scanner for bushes is particularly designed to offer correct and quick outcomes with out destroying bushes. The system features a gamma metering nozzle 3-4 occasions sooner than the common. It’s related to a computerized system that drives the remote-controlled belt and is mounted on a hydraulic forklift.

“The gamma ray scanner has a nozzle 3-4 occasions sooner which makes the main target of the beam comparatively decrease and due to this fact not harmful to the individual utilizing it. It solely takes 10 minutes to examine the situation of 1 place of the tree, and if mandatory, scanning may be achieved from a number of angles or repeatedly for higher accuracy on every scan.

To examine the tree, the system needs to be used on a flat floor with a large circumference which is able to enable a forklift or hydraulic car to simply attain the tree. If the trunk seems to be hole, then a tree assist system is put in for added assist, or cement is injected into the hole half.

Clear bushes for the advantage of Chola and the group

Since 2019, the Division of Nuclear Expertise, Faculty of Engineering, Chulalongkorn College has used a gamma ray tree scanner as a part of the Chola Massive Tree Challenge beginning with 5 Shamchori bushes (rain bushes) planted by His Majesty King Bhumibol greater than 60 years in the past. . Sadly, a fifth of those bushes fell because of a rainstorm earlier than the screening challenge started. Two of the bushes have been discovered dangerously hole however the college held that every one 4 current bushes have been supported by metal rods.

These missions proceed to today. Aside from the 4 rain bushes subsequent to the Maha Chulalongkorn constructing, different outdated bushes within the Faculty of Engineering and different faculties on campus have been checked for the security of all Chula college students and employees.

The Ministry of Nuclear Expertise has additionally repeatedly acquired requests from different companies exterior Chola to offer this survey service. Lately, three 80-95 cm vast rainforest bushes have been examined alongside the canal on Soi Somkid between the Chidlom Central Purchasing and Embassy malls. The world is about for panorama improvement with the addition of a pedestrian bridge resulting in Khlong Saen Saeb. Because of some limitations, as a result of the house may be very tight, the scanning system wanted to be re-designed with a decrease measurement and weight. The manufacturing of this modified model took solely 5 days and the outcomes of the survey confirmed big hole areas in all three bushes.

“The Ministry of Nuclear Expertise additionally used low-power gamma scanning tools to scan cracks and decide the power of as much as 140 teak columns chosen to be used within the development of Thailand’s new Parliament constructing. The challenge comes beneath the route of Affiliate Professor Shadit Yinchai. We anticipate that sooner or later these may be developed The tools is additional made simpler to make use of with an automatic system that allows us to see vertical pictures contained in the bushes. This may even rely on the price range that may be allotted to this challenge.” assistant. Professor Nares added.
