Radiation levels are dropping somewhat at Japan's disaster-stricken Fukushima Daiichi nuclear power plant. The government's nuclear safety agency says it will continue to monitor the situation carefully.
The Tokyo Fire Department poured water into the plant's Number 3 reactor for 6.5 hours on Sunday night in a continuing attempt to cool down a storage pool for spent fuel.
The Self-Defense Forces meanwhile shot water into the Number 4 reactor on Sunday, and again on Monday morning.
The Nuclear and Industrial Safety Agency says the operations appear to be paying off to a certain degree, with radiation levels showing a continuous decline since Sunday afternoon.
