He said countries worldwide were taking note of the incident at a nuclear plant in Japan following Friday's earthquake and tsunami, and many lessons would be learned from it.
"What is important is the security of the people and the nation.
"We have an agency responsible for such matters which knows what it is doing and we believe it will do what is best," Muhyiddin said after closing the 1Malaysia Family Adoption programme here yesterday.
Last year, the government announced plans to build two nuclear power plants to generate 1,000MW of electricity each, with the first plant expected to begin operations in 2021 and the second, a year later.
The explosion at the nuclear plant in Fukushima, however, had caused many to question the plan.
Muhyiddin also advised Malaysians not to fall for rumours and text messages regarding radiation from Japan coming to Malaysia through rain.
He said such text messages were the work of irresponsible parties.
"We should always check. If there was any danger, the authorities would inform us."
He said the government was constantly monitoring the situation and statements from recognised bodies on the matter.
