Powerplus Systems Ltd was established 20 years ago and works primarily in the irradiation field. Even if you are in the irradiation industry you may not have heard of our company. This is because until recently our products and services were branded by and only available through other companies. Back in the early 1980’s our services were only available through Marsh Irradiators International Ltd. They were taken over by NUKEM GmbH then subsequently by REVISS/PURIDEC. During that entire time Powerplus services were only available exclusively through these companies.

However, we have recently renegotiated our contract and we are free to supply goods and services directly to the end user.

This removal of the middle man allows our pricing to be far more competitive.

September 2004: Powerplus Systems Ltd have been chosem by the Malaysian Institute of Nuclear Technology to provide a state of the art caesium-137 Gamma Greenhouse facility.

June 2003: Professor Siranut Lamseejan was chosen as this years outstanding nuclear scientist for her success in whitening pink chrysanthemums using a gamma greenhouse shown below which was installed by Powerplus Systems Ltd in 1997/8.

Meanwhile, in Thailand, the Asian country perhaps most often associated with orchids through its national airline's custom of presenting every passenger with an orchid, a range of new mutants of several popular flower species have been developed using nuclear technology. At Kasetsart University, Bangkok, Professor Siranut Lamseejan has led a team that has developed some 90 mutants of chrysanthemum alone. "We have a very big market for chrysanthemums in Thailand and currently we have to import from other countries," says Prof. Lamseejan. "So, we want to develop new varieties to satisfy our own market, even before we export." Using the technique of radiation-induced mutation, they can change the shape, size and colour of flowers. But, before release onto the market, Prof. Lamseejan invites growers and florists to inspect plots of all new cultivars to advise which, in their professional opinion, have market appeal. "I may think a flower is beautiful," says Prof. Lamseejan, "but if the growers and florists don't thinks it will sell, we reject it." Currently, four leading cultivars of chrysanthemum are being tested for market acceptance.

The Gamma Radiation and Nuclear Technology Center at Kasetsart, where this work has been done, has received valuable guidance and technical assistance under a Technical Cooperation Project of the FAO-IAEA Joint Division, based at International Atomic Energy Agency headquarters in Vienna. In turn, the Center at Kasetsart has been able to share its experience with visitors form China, Japan, Malaysia and Vietnam.

Work has also been initiated on roses, anthuriums and orchids, of which there are over 1,000 species in Thailand. Prof. Siranut Lamseejan's team has also produced mutants of portulaca, by irradiation of stem cuttings, and curcuma and canna lily, by irradiation of rhizomes. Canna lilies are a popular ornamental plant grown widely in Thailand, and Prof Lamseejan's work has been marked by the naming of an outstanding new canna variety, 'Orange Siranut'.
